摘要

A PROCESS TO PRODUCE O-SILYL O,N-KETENE ACETALSABSTRACTA process for preparing O-silyl O,N-ketene acetalshaving the formula,R2C=C(OSiRnX3-n)(NRa2) or.The process comprises contacting an alpha-haloamide with analkali metal in the presence of an excess of an organohalo-silane, the alpha-haloamide having the formula, or ;the organohalosilane having the formula,RnSiX4-n ;and facilitating reaction among the alpha-haloamide, thealkali metal and the organohalosilane to form the O-silylO,N-ketene acetal and alkali metal halides.
