摘要

While thermolysis of 1-benzyltriptycene la in the gas phase at 600° C/10 mmHg did not result in any appreciable decomposition, similar pyrolysis of compounds 1 bearing various substituents (X) at the benzyl methylene (1b–d) underwent smooth decomposition to give 8- benzylbenz [] aceanthrylene 2. The reaction is explai
