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 reactivity cycloaddition reactions. The reaction phenyl(ethyl)-, phenyl(trimethylsilyl)- trimethylsilylketenes with diazomethane at −78°C is described. Only 2 1 cycloadducts, cyclobutanones, could be isolated.
