The reaction of diphenyldiazomethane with 2,3-dichloro-5,6-dicyano-benzoquinone in the presence of alcohols and thiols gave the corresponding benzophenone acetals and thioacetals at 20–25°C in 1,2-dichloro-ethane. The mechanism of the reaction will be discussed.
在醇和硫醇存在下,二苯基重氮甲烷与2,3-二氯-5,6-二氰基-苯醌的反应在1,25-二氯乙烷中于20–25°C下得到相应的二苯甲酮乙缩醛和硫缩醛。将讨论该反应的机理。
