Organogallium formation

This method bears some similarities to the Grignard Reagent method in that product formation is often accomplished with solvent association. In particular, this method has been useful in preparing sterically demanding organogallium compounds, (Aryl)3Ga (vide infra). 

The heterogeneous decomposition mechanism is characterized by easy chemisorption followed by rapid decomposition. Again the presence of adsorbed organogallium species catalyses this process, thus the formation of GaAs is a synergetic, mutually catalytic process. 

Colored solutions were formed when GaC was dissolved in benzene or toluene, and this was ascribed to the arene complex formation of the Lewis acid. The treatment of the complex formed from methylnaphthalene with D2O resulted in random deuteration at the aromatic nuclei (Scheme 7.55) [88]. No deuteration occurred at the methyl group. The lack of selectivity in the orientation suggested the deuteration of the organogallium intermediate.
