The reaction between trimethylsilyldiazomethane and aryl or vinyl ketenes 2 and 7, bearing an electron withdrawing group on the ketene moiety, gave rise in moderate to good yields to the trimethylsilylated styrenes 3–5 or 1,3 dienes 8a-d resulting from the decarbonylation of presumed intermediate cyclopropanones.
三甲基甲硅烷基重氮甲烷与在烯酮部分带有吸电子基团的芳基或乙烯基烯酮2和7之间的反应,由于三甲基甲硅烷基化的苯乙烯3-5或1,3二烯8a-d的脱羰作用,中等至良好的收率。假定为中间环丙烷。
