Abstract

  • Me Ga was allowed to react with a series of ten amines at 110°C in toluene to give 75 to 90% yields of the corresponding aminogallanes, [Me GaR] [R = NMe , NEt , NPr , NBu , NBu , N(c-C H ) , NC H , NC H , NC H , and N(CH CH ) NMe], via a 1,2-elimination of CH . Similarly, [Me A1NBu ] and [Me A1N(c-C H ) ] were prepared by an analogous thermolysis reaction. On the other hand, synthesis of [Me GaNPr ] , [Me GaNBu ] , and [Me GaN(CH Ph) ] was achieved by the reaction of Me GaCl with the respective lithium amide. A comparison of the H and C NMR chemical shifts for the aminogallanes with those previously obtained for the analogous series of aminoalanes indicates a similar sensitivity to the influence of the amide moiety. X-ray crystal structures were determined for [Me GaN(CH Ph) ] , which has a slightly puckered four-membered Ga N core, and [Me GaN(CH CH ) NMe] , which has a planar four-membered Ga N core. © 1997 Elsevier Science S.A. 3 2 2 2 2 2 2 2 6 11 2 4 8 5 10 6 12 2 2 2 4 2 2 2 2 6 11 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 n n i s i s 1 13
