The photoreactions of a number of biphenyl derivatives, in particular nitrobiphenyl derivatives, with cyanide ion have been investigated. Photosubstitution by cyanide ion has been found to predominate; photoreduction is not observed. In some cases (4-nitrobiphenyl, 4,4′-dinitrobiphenyl, 3-nitrobiphenyl and similar compounds) the behaviour can be rationalized on the basis of analogy to the pattern of
已经研究了许多联苯衍生物,特别是硝基联苯衍生物与氰化物离子的光反应。已发现氰化物离子的光取代占主导地位。未观察到光还原。在某些情况下(4-硝基联苯,4,4'-二硝基联苯,3-硝基联苯和类似化合物),可以根据与联苯本身的光致氰化模式相似的方式来合理化行为(优先选择取代4位) 。辐射后的2-甲氧基-4-硝基联苯和2-甲氧基-5-硝基联苯与氰化物离子按照硝基苯甲醚而不是不含甲氧基取代基的硝基联苯的模式反应。在光激发的2,4,6-三甲基联苯中,氰化物离子进攻的有利位置似乎在3-位,即
