Hydrogen elimination from secondary amine and phosphine adducts of gallium hydride

Abstract

The new compounds Me2NH,GaH3 and Me2PH,GaH3 have been synthesised and their physical and chemical properties investigated. Gas-phase displacement reactions have shown that the order of donor power towards gallium hydride for the various ligands employed lies in the order Me2NH > Me3N ∼ Me3P > Me2PH. Intramolecular hydrogen elimination from these compounds yields Me2NGaH2 and Me2PGaH2 respectively, and has been followed by both infrared and proton n.m.r. spectroscopy. The infrared spectrum of Me2NGaH2 indicates that the compound is monomeric in the gas phase and is thus the first example of a stable tri-co-ordinate gallium hydride derivative; it is dimeric in benzene solution.

Attempts have been made to prepare higher analogues of adducts in the phosphine series, namely, Et2PH,GaH3 and Ph2PH,GaH3, but these proved to be of low stability. The stability relationships existing between the compounds prepared in this work and similar compounds of boron and aluminium are discussed.
