摘要

Demands for sustainable and ecologically friendly organic syntheses have led to investigations of the conditions involved in reactions. 1 Among these conditions, solvent-free strategies 2 and the use of water 3 as the reaction medium represent important alternatives. Very recently, Sharpless and co-workers 4 reported an important observation that some organic molecules can react on the surface of water, and in some cases very strong enhancement in the reaction rate was ...
