with a minor amount of indene dimer. The former isomers can be equilibrated with strong base. Adducts of 1,1-dimethyl- and 1,1-diphenylindene with acrylonitrile are also described, and nuclear magnetic resonance data reported. Naphthalene adds acrylonitrile on photolysis in t-butyl alcohol (pyrex filter) to afford trans-8-cyano-2,3-benzobicyclo-[4,2,0]-octa-2,4-diene (90%) and 1- and 2-naphthyl-2-propionitrile
研究了茚和萘与丙烯腈的光解反应,并对产物进行了表征。当碳氢化合物吸收光时,或当三线态敏化剂(苯乙酮)吸收光时,茚与丙烯腈发生反应。在乙醇中的前一种条件下光解产生 2-(1-茚基丙腈) (70%)、2-(3-茚基丙腈) (10%) 和 6-氰基-2,3-苯并双环 [3,2,0]hept -2-烯(20%)。报道了取代茚的碱催化异构化。敏化时,形成 7-氰基-2,3-苯并双环[3,2,0]庚-2-烯的顺式和反式异构体,以及少量茚二聚体。前一种异构体可以用强碱平衡。还描述了 1,1-二甲基-和 1,1-二苯基茚与丙烯腈的加合物,并报告了核磁共振数据。萘在叔丁醇(耐热玻璃过滤器)中光解时加入丙烯腈,得到 trans-8-cyano-2,3-benzobicyclo-[4,2,0]-octa-2,4-diene (90%) 和 1-和 2-萘基-2-丙腈 (10%)。敏化...
