摘要

Abstract Phenyl (trimethylsilyl) ketene was prepared by the zinc dehalogenation of phenyl (trimethylsilyl) bromoacetyl chloride. This ketene parallels tirmethylsilylketene in stabibility and lack of reactivity in cycloaddition reactions. The reaction of phenyl (ethyl)-, phenyl (trimethylsilyl)-and trimethylsilylketenes with diazomethane at− 78 C is described. Only the 21 cycloadducts, the cyclobutanones, could be isolated.
