    Microwaves Aren’t Magic

    Many synthetic chemists these days use microwave reactors to speed up their reactions, especially metal-catalyzed couplings. But there’s been a debate ever since the technique became popular about why it works so well. Some people think that microwave irradiation is just a very efficient and fast way to heat up a reaction, while others have… Read More

    Nobel Season 2009

    Fall is in the air, which (for a very small group of people) brings thoughts of a call from Stockholm. The Nobel Prizes will be announced next week, starting the Physiology and Medicine on Monday. And as in years past, people are lining up with predictions. Predicting the Chemistry prize is tricky, since it’s so… Read More

    Chew On This, Enzyme

    File this one under “Department of Odd Ideas”. There’s a paper coming out in JACS that has a neat variation on an idea that’s been kicking around for some years now: molecularly-imprinted polymers (MIPs). A MIP is a sort of molded form around some molecular template – you make your polymer in the presence of… Read More

    More on T2, and Degrees

    Friday’s article on the T2 explosion has had a lot of readers, thanks to links from various outside sources. One line from it has attracted a disproportionate amount of comment – the one where I mentioned that the two owners of the company had only undergraduate degrees. This needs some clearing up; I should have… Read More

    175 Times. And Then the Catastrophe.

    I noted this item over at C&E News today, a report on a terrible chemical accident at T2 Laboratories in Florida back in 2007. I missed even hearing about this incident at the time, but it appears to have been one of the more violent explosions investigated by the federal Chemical Safety and Hazard Board… Read More

    “Scratch and Sniff” Turns Into “Zap and React”

    Here’s an odd idea that might turn into something useful. A group at Berkeley (spanning both the chemistry and physics departments of Cal-Berkeley and the Lawrence labs) have reported a method for encapsulating organic molecules and releasing them inside a reaction when needed. What they do is form microcapsules, small polymer spheres, from b… Read More

    Another Iron Reaction Hits The Mat

    Beware of iron! That’s the lesson that’s being hammered home these days in synthetic chemistry. I wrote recently about the discovery that a series of iron-catalyzed couplings were actually being caused by trace amounts of copper compounds. Now there’s another re-examination of some similar iron couplings that were reported last ye… Read More

    Rings of the Future!

    Here’s an interesting paper that some of you may have seen in J. Med. Chem.: “Heteroaromatic Rings of the Future”. That’s an odd title, but an appropriate one. For the non-chemists in the crowd who made it to this paragraph, heteroaromatic rings are a very wide class of organic compounds. They’re flat cyclic structures… Read More

    Everything In Its Place

    Things are pretty quiet around the industry these days, so my blogging thoughts have been turning to Big General Problems. And here’s one that I know that people are working on, but which I think we as chemists are going to have to understand much better: localization. “Say what?” is the usual response to that… Read More

    The Further In You Go, The Bigger It Gets

    I had a printout of the structure of maitotoxin on my desk the other day, mostly as a joke to alarm anyone who came into my office. “Yep, here’s the best hit from the latest screen. . .I hear that you’re on the list to run the chemistry end. . .what’s that you say?” This… Read More
