Chemists Synthesize "Impossible" Molecule

neilest writes "Organic chemistry textbooks will need to be revised to recognize a chemical species that chemists have discovered at Northwestern University. The species -- pentamethylcyclopentadienyl cation -- was thought not to exist for long because theory said it was unstable. The full story can be found at this suntimes article"

    "I've said this molecule is unstable and doesn't exist dozens of times in organic chemistry class, but as it turns out, the molecule had different ideas," Northwestern chemistry professor Joseph Lambert said.

    Q: You've been calling something unstable for a while, but it turns out it was stable. What do you do?

    A: Increment the version number and release it!

    "The Omelette" - A retort to Malda's Omelette analogy.

    Let me try to give you an analogy for Slashdot's homepage.
    Yes, please liken something to something in a cliché staid analogy because we the reader are too stupid to understand any overly complex and high level reason why you can't explain yourself properly. Either that or you are full of crap, don't know what you are doing and are lucky as hell to have what you have.

    It's like an omelette: it's a combination of sausage and ham and tomatoes and eggs and more.
    It is a motley collage, a miasma, a montage or eclectic and seemingly unrelated things. It may be a myriad of unrelated things, related at only the most abstract levels. It certainly isn't an omelette.

    Over the years, we've figured out what ingredients are best on Slashdot.
    What critical acclamations have you had that makes you think this is so? Just because you get a lot of hits, and subsequently subject your readership to unwanted bandwidth consuming detritus, doesn't mean you know what's best. It is just like a Reynolds family member claiming they know what's best for them, nicotine and smoke are not unhealthy, and then they die of lung cancer. You are an egotistical megalomaniac. If this site was run based on a meritocratic method rather and juvenile selfishness, it would have serious potential.

    The ultimate goal is, of course, to create an omelette that I enjoy eating: by 8pm, I want to see a dozen interesting stories on Slashdot.
    The ultimate goal is to please yourself, to feed your id. You have no desire to please the community by which you make your living. You are selfish, sheltered and removed from your community. You are on a one way soapbox, a pulpit, and you talk at people. I would probably include you in a list of people I would kill if I could get away with it.

    I hope you enjoy them too.
    I do not.

    I believe that we've grown in size because we share a lot of common interests with our readers.
    Mobocracy is good? You would rather collect people without regard to quality. This means nothing. Budweiser is the most consumer beer, but its garbage. This is analogous to Slashdot, to stoop to your food and beverage analogy. Bud beer. Its good because a lot of people drink it. No, no. Don't bother trying to get critical acclimation. Don't bother, you know as long as you "control" Slashdot, you never will.

    But that doesn't mean that I'm gonna mix an omelette with all sausages, or someday throw away the tomatoes because the green peppers are really fresh.
    So serving rotten food is acceptable how? Its better to keep your silence and let people wonder if you are fool than to speak up and remove all doubt. "Gonna." Pathetic. Simply pathetic. This is a hick like expression, akin to something on the order of, "I'm gonna open a can of whup ass on him for peggin Mary Joe Susie Lee."

    There are many components to the Slashdot Omelette. Stories about Linux. Tech stories. Science. Legos. Book Reviews. Yes, even Jon Katz.
    Jon Katz is the worst thing about this place. If it isn't the wasting of my bandwidth that I pay for, its this that bothers me the most. On a sidebar, I would like to hold you and the rest of the scum who send ad banners to my connection legally liable for unwanted bandwidth usage. This crap half the time doesn't even come from your site. It would be less of an affront if you stored you vile ads on your own site, but you took the easy way out and decided to outsource the production of garbage to similarly-devoid-of-ethics people with slightly more intelligence and infrastructure to provide this illegal content.

    By mixing and matching these things each and every day, we bring you what I call Slashdot. On some days it definitely is better than others, but overall we think it's a tasty little treat and we hope you enjoy eating as much as we enjoy cooking it.
    Grotesque things are often of huge interest to people. This holds true with me in regards to Slashdot. I hate you, I hate Jon Katz, I hate most of the content here. Some of the best stuff is written at -1. You would suppress those who are different while you are "different like everyone else," just another marginally educated half assed "programmer" who on the scale of things lucked out even more so than Bill Gates (reason: I would assume your IQ is probably his divided by 2 or 3 and you aren't working at a McDonald's where you should be). Whenever you have participated in a discussion thread, you are obnoxious, rude and ungrateful. You policies are horrible, you content is basically a smattering of other people's work and you benefit from this. You web page reeks of someone who completes nothing that he starts. Your obsession with anime is a testament to how juvenile you are, your spelling is horrific, you grammar is oft questionable; you are a poor editor Mr. Malda.

    I hope only the worst outcomes for any and all of your endeavors henceforth. I hope your fiancée or if you are lucky, your marriage falls apart. I hope your Jubei breaks. I hope you lose your job. I hope that you fail because you are displacing true talent.

    The artical was short, and missing one major detail...What is it? If it was considered unstable, but now seems to be stable, wonderfull, but does it have an usefull purposes? I want the modified sugar molecule that has the proper atoms reversed so the body doesn't process it....Now that would be usefull. We could have all the sweet things we crave and never gain weight for it.

    If they figure that one out that would be worth a nobel prize.

      The said it was "a pentamethylcyclopentadienyl cation" which tells you exactly what they made if you have the right secret decoder ring.

      penta- means five -methyl- refers to a methane group; a methane group is a carbon with all it's free bonds capped with hydrogen.
      pentamethyl- means it has five methyl- groups dangling off of it; they don't tell us where, but we'll shortly see why they didn't bother.
      -cyclo- means the base structure is a ring. -penta- is five again -dienyl- means alternating single and double bonds like so ...--C==C--C==C--C==...
      -cyclopentadienyl- means that it's a ring of five carbons with every other other bond double. But wait, you say, what does "every other mean" in a five element ring? Thus we get to...
      -cation means it's got a positive charge, so the whole bonding picture may be off, with the double bonds playing resonance leap-frog around the ring.
      So (in English) it's a positively charged ring of five carbon atoms, with a CH3 hanging off each carbon, and an average of 1.4 bonds between each pair of carbons in the ring.

      As for what it's good for, that depends. It could be good for a thesis, or for tenure, or for funding, or...it all depends on where you are in the food chain.

      From the horse's mouth:
      Our research is aimed at synthesizing new classes of molecules with useful and interesting electronic, optical, conformational, and spectroscopic properties. Many, but not all, of these molecules contain main-group elements such as silicon, germanium, sulfur, and phosphorus. We have recently prepared the first stable, three-coordinate silyl cations and the first stable cyclopentadienyl cation.
      This sounds like it might conceivably be useful for a lot of things.
