Abstract

The covalent derivatives [Et2M-PEt2]3 (M = Ga, In) have been prepared from Lewis acid-base complexes, R3M.PHEt2, by alkane elimination and characterized by elemental analyses, IR, 1H and 31P NMR spectroscopy. Features of the mass spectra reveal a trimeric form and the strength of the [M-P]n ring. For the compound [ClMeGa-PEt2]n, spectral data are consistent with a weakening of the [Ga-P]n chain, in good agreement with the pyrolysis results.
