Abstract

Abstract The first germapyrazoline, 4-germa-1-pyrazoline (2), has been obtained by [2+ 3] cycloaddition of diazomethane to the Ge C bond of the germene (1). Thermal or photochemical decomposition of 2 via a germirane intermediate (4) gives 9- methylenefluorene and dimesitylgermylene, which can be trapped by 2, 3- dimethylbutadiene.
