Abstract

Abstract Addition of the primary phosphine t BuPH 2 or the primary arsine t BuAsH 2 to t Bu 3 M (M Ga, Al) followed by heating or photolysis affords the complexes [t Bu 2 M (μ-E (t Bu) H)] n,(1: M Ga, E P; n= 2; 2, M Al, E P, n= 2; 3, M Ga, E As, n= 3; 4, M Al, E As, n= 3). For each compound, the degree of association was assessed on the basis of 1 H 31 P, 13 C NMR and mass spectroscope. The anti-isomer of 1 (1a) was also characterized by ...
