Name reactions: how does the label stick? Some of these names go back to the 19th century, and many more of them come from the first decades of the 20th. Once in a while, I wonder if the tradition is dying out. Are we still naming chemical reactions after their discoverers? mark for My Articles similar articles

Ultrafast NMR shows the way Chemists have created an ultrafast NMR technique that can 'watch' how chemical reactions occur in real time. They've used the technique to follow the formation of pyrimidines from carbonyls and even identified new intermediates never before thought to be part of the reaction. mark for My Articles similar articles
