Aryltriethylgermanes and diethyldiphenylgermane were found to split easily to generate germyl radicals by irradiation with a medium-pressure mercury lamp in hexane or cyclohexane. The germyl free radicals produced reacted with hydrocarbon radicals generated from the solvent by hydrogen abstraction either by recombination or by disproportionation.
A facile cleavage reaction of the germanium–carbon bond of (germylmethyl)amine derivatives to give a germyl anion and an azomethine derivative was developed. The effects of substituents such as phenyl, benzyl, and ethyl groups on the germanium and nitrogen atoms of the (germylmethyl)amine derivatives on the cleavage reaction, were investigated. The mechanism was also investigated based on the stereochemistry
