Icanhasscience (check it out!) notes in the comments that the AP's other report on the palladium Nobel prize used the analogy of a singles bar for palladium-catalyzed cross-couplings. That article is one of the few in the media that didn't seem to use the "matchmaker" meme to describe the reaction.
I'm terribly curious -- who was the first reporter or news outlet to use this analogy? I've never heard metal cross-couplings described this way; I have to admit it's a fairly accurate picture to describe the reaction mechanism. With the help of Google, I see that on October 6, USA Today, Scientific American, New Scientist, Agence France-Presse, NIKKEI.com, Christian Science Monitor, Science Now and MSNBC.com all used the "matchmaker" meme. Is it the quoted Jeremy Berg? Inquiring minds wish to know.
P.S. Has any other chemist heard Pd reactions described this way? Am I the only crazy one who hasn't?
