【摘要】 <正> 关于二氯卡宾与烯烃基硅化合物加成反应的研究,迄今只有 Cudlin 等所发表的论文。他们使氯仿和叔丁醇钾作用得到的二氯卡宾与烯烃基三甲基硅烷进行亲电子加成,合成三甲硅烷基二氯环丙烷衍生物,并曾研究三甲硅烷基对处于不同位置上双键加成速率的影响。更多还原

【Abstract】 By refluxing allylsilicon compounds（Ⅰ）with anhydrous sodium trichloroacetate in1,2-dimethoxyethane,the dichloromethylene produced by the decomposition of sodiumtrichloroacetate was found to add to the allyl group in the expected manner to give thecorresponding dichlorocyclopropane derivatives（Ⅱ）:（?）The compounds synthesized are:Compound R R′ B.P.°C/mm d₄²⁰ n_D²⁰ Yield %Ⅱa CH₃— CH₃— 78—9/20 1.0380 1.4611 8.4Ⅱb C₂H₅O— C₂H₅O— 110—2/5 1.0860 1.4498 15Ⅱc C₂H₅O— CH₃— 92—4/4 1.0406 1.4623 12.2Ⅱd C₂H₅O— CH₂=CHCH₂— 110—4/4 1.0857 1.4610 18更多还原
