摘要

Nucleophilic ring opening of oxiranes 1 and 2 by the carbanion AH- ("anthracene hydride") proceeds rapidly giving rise to two isomeric products 3 and 5 from styrene oxide 1. In prolonged reactions, products with a 9-benzyl 9,10-dihydroanthracene structure (5, 6) are fragmented by an excess of carbanion to yield anthracene A and benzylic anions. The respective products 7 and 8 of reductive opening can be isolated in good yields with Na+ as gegen ion; however, they are transformed into styrenes with Li+. No fragmentation was observed in reactions of styrene oxide with xanthenyl anion Xan-.
