摘要
A facile and efficient method for the preparation of methyl ketones was developed in the reaction of alkynes and alkenes with PhIO-BF3·Et2O.The reaction features mild conditions,short time and metal-free catalyst.The possible mechanism for the formation of methyl ketones was proposed.H2O functions as both a nucleophile and an oxygen source.
