Addition of t-butylcyanoketen to 3,3-dimethylcyclopropene and 1,3,3-trimethylcyclopropene gives mixtures of the bicyclo[2,1,0]pentan-2-ones (3a,b) and rearranged products (4a,b) and (5b); the ketone (3b) rearranges to (6b) but not to (4b).
将叔丁基氰基酮加到3,3-二甲基环丙烯和1,3,3-三甲基环丙烯中可得到双环[2,1,0]戊烷-2-酮(3a,b)和重排产物(4a,b)的混合物(5b);酮(3b)重排至(6b),但不重排至(4b)。
