Abstract
The novel digallanes [GaN(Dipp)CH=CHN-(Dipp)](2) (3) (Dipp = 2,6-diisopropylphenyl) and [GaN-(Dep)CH=CHN(Dep)](2) (4) (Dep = 2,6-diethylphenyl) were obtained in quantitative yield by photolysis of the 1-galla-2,5-diazoles [(eta (1)-Cp*)GaN(Dipp)CH=CHN(Dipp)] (1) and [(eta (1)-Cp*)GaN(Dep)CH=CHN(Dep)] (2), respectively. This alternative approach to the synthesis of digallanes demonstrates the efficiency of the Cp* moiety as the leaving group in the formation of metal-metal bonds. Compounds 3 and 4 were characterized ky spectroscopic and analytical data. Compound 3 could further be characterized by X-ray crystallography; its molecular structure is compared with the structures of some other digallanes. Density functional calculations for differently substituted digallanes are presented.
