Abstract

Reaction of GaMea with 7V,AT-dimethylethylenediamine (DMEDA) produces adducts, Me3Ga:NH2C2H4NMe2 (1:1, 1) and Me3Ga:NH2C2H4NMe2:GaMe3 (2:1, 2). A fast concerted intermolecular exchange of the two inequivalent GaMea moieties occurs in 2 at room temperature. Thermolysis of 2 at 210 °C in a sealed ampule produces a mixture of cis and trans isomers of tetrametallic imidogallane, [Me2Ga(//-NC2H4NMe2GaMe2)]2 (3). Slow recrystallization of 3 affords only the cis isomer as colorless crystals, but in solution the cis isomer equilibrates with the trans isomer.
