Crazy Shape-Shifting Bullvalenes
It's a funny-looking symmetric tricyclic compound, which just seems to be another weirdo hydrocarbon until you consider what it can do with all those alkenes.
New Ways to Fluorinate
Over at New Reactions, there's a nice writeup on a new way to generate difluorocarbene, which (as it should) immediately adds to alkenes to give you difluorocyclopropanes.
This Week in Science
Surprisingly, the vanadium-dependent variety of nitrogenase was recently shown to reduce CO and to catenate the intermediates by carbon-carbon bond formation, yielding small alkanes and alkenes. Hu et al. (p.
