摘要：

Flash vacuum pyrolysis of the allyl esters 2 (X=O,S, CH2, CO) at 900-degrees-C (10(-2) Torr) gives dibenzofurans, dibenzothiophenes, fluorenes, and fluorenones respectively as the major products. The mechanism involves the phenyl radical intermediates 1 which equilibrate by intramolecular hydrogen transfer via six-membered transition states, prior to cyclisation.
