摘要

The Schmidt rearrangement of substituted 3-phenyl-2-butanone with trimethylsilyl azide in 90%(v/v) aqueous TFA gave two types of product, fragmentation and rearrangement, the ratio of which depends on the substituent: more fragmentation for a more electron-donating substituent. Rate measurements by azotometry indicated the presence of an induction period, and the pseudo-first-order rate constants showed saturation kinetics with respect ...
