Carbenes3a-e add to the α-side of the first double bond of dienamine2 (title compound) to give 1 : 1 adducts4a-e, Chlorofluorocarbene3e gives, in addition, ketone7, corresponding to β-addition at the second double bond of2, and a 2 : 1 adduct8. The reaction of2 with dichlorocarbene3a yields, besides4a, novel ring-expansion products5 and6 corresponding to addition of two moles of3a. Ethoxycarbonylcarbene3f
卡宾3a-e加到二烯胺2(标题化合物)的第一个双键的α侧,得到1:1加合物4a-e,氯氟卡宾3e产生酮7,相当于第二个β加成的双键2和2:1个加成物8。的反应2与二氯卡宾3a中的产率,除了图4a,新颖环膨胀制品5和6对应于添加两个摩尔的3A。乙氧羰基卡宾3f与二烯胺反应(2)得到异构酯9和10a,b。讨论了反应产物的结构分配和形成机理。
