Acid-catalyzed rearrangement of 6-phenylbicyclo[3.2.0]heptan-6-ol gave 1,1′-biphenyl and 1,1′-biphenyl-carbaldehydes in small amounts as well as the expected rearrangement products. A detailed study of the reaction mechanism revealed that the conversion occurs via an oxidative process through the consecutive formation of cycloheptadienes, cycloheptatrienes, and 1,1′-biphenyls. The acid-catalyzed rearrangement
酸催化的6-苯基双环[3.2.0]庚-6-醇的重排生成了少量的1,1'-联苯和1,1'-联苯-甲醛以及预期的重排产物。对反应机理的详细研究表明,转化是通过连续形成环庚二烯,环庚烯和1,1'-联苯的氧化过程发生的。酸催化的6-苯基双环[3.2.0] hept-2-en-6-ols重排直接生成1-和2-苯基环庚烯,其中1,1'-联苯和1,1'-联苯基-甲醛通过氧化获得。
