Irradiation of a benzene solution containing 1-diphenylvinylidene-2,2,3,3-tetramethylcyclopropane and an excess of acrylonitrile in the presence of Michler's ketone afforded 2-cyano-1-diphenylvinylidene-4,4,5,5-tetramethylcyclopentane in high yield.
在米氏酮存在下,辐照含1-二苯基亚乙烯基-2,2,3,3-四甲基环丙烷和过量丙烯腈的苯溶液,得到2-氰基-1-二苯基亚乙烯基-4,4,5,5-四甲基环戊烷屈服。
