GALLIUM HYDRIDE ADDUCTS OF TRIMETHYLPHOSPHINE AND TRIPHENYLPHOSPHINE,
Abstract
The new compounds Me3PGaH3 and Me3PGaD3 were prepared and shown by their gas-phase infrared spectra to be monomeric. The P-Ga stretching frequency was identified at 326/cm. The absence of a 2:1 adduct, (Me3P)2GaH3, was shown by tensiometric titration at -21C. Gas-phase displacement reactions indicate that trimethylamine and trimethylphosphine have similar donor strengths towards gallium hydride. The corresponding aluminium hydride adduct Me3PAlH3 could not be prepared directly, and trimethylphosphine does not displace trimethylamine from Me3NAlH3. The compound Ph3PGaH3 was prepared but readily decomposes at room temperature. The equilibrium between trimethylamine, trimethylphosphine, and their adducts with gallium hydride in benzene solution was investigated by n.m.r. spectroscopy. (Author)
