Abstract
The Michael reactions of 2-chloro-and 2, 7-dichloro-9, 9′-bifluorenylidenes with fluorenes were investigated. Structures of these products were confirmed by syntheses through the well-established reactions of 9-lithiofluorenes and 9-bromo-9, 9′-bifluorenyls. The formation of some abnormal compounds is explained by intermediary formation of 2, 7- dichloro-9, 9′-bifluorenylidene from the reaction of 9, 9′-bifluorenylidene with 2, 7- ...
