The mechanism for the photodecomposition of several o-diazonaphthoquinones has been examined in acetonitrile solution using time-resolved laserflashphotolysis techniques. It is concluded that the Wolffrearrangement, which involves the formation of a ketene intermediate, can be regarded as a concerted process in the nanosecond time scale. It is suggested that the reaction of the ketene with water
