Abstract

9-Diazofluorene (DAF) is decomposed either stoichiometrically or catalytically in the presence of the platinum (0) complex [Pt (C2H4)(PPh3) 2] to give difluoren-9-ylidene- hydrazine in high yield. Under analogous reaction conditions, diphenyldiazomethane gives mostly the azine, Ph2C N N CPh2, while ethyl diazoacetate (EDA) affords, in low yield, a mixture of diethyl fumarate and maleate in approximately 10: 1 molar ratio. The ...
