摘要: 二氯卡宾与四苯基环戊二烯酮(1)反应放出CO,并生成偕二卤化物(3)、二氯环氧乙烷(4)以及双键加成物(5).羰基叶立德的芳香性结构及其“中介型”构象决定了该反应以脱CO为主,电环化途径次之.

关键词: 卤代卡宾, 羰基叶立德, 脱氧

Abstract: The reaction of dichlorocarbene with tetraphenylcyclone (1) resulted in carbon monoxide and gem-dichloro compound (3) together with dichlorooxirane (4) and adduct (5).The aromatic structure of carbonyl Ylide and its twist geometry led to deoxygenation to be the main reaction pathway.

Key words: Halocarbene, Carbonyl Ylide, Deoxygenation
