摘要
Flow-vacuum pyrolyses of the title hydrocarbons afford anthracene and 9-methylanthracene as main products. The reaction mechanism suggested by Trahanovsky(2) for pyrolysis of dibenzocyctooctene- and dibenzocycloheptene derivatives is confirmed. For secondary products, parallel radicalic routes are suggested.
