摘要:
                                The first base-stabilized phosphino- and arsinoalane monomers, H2AlEMes2.NMe3 (Mes = Mesityl; 1, E = P; 2, E = As) have been prepared. Thermolysis at 95-degrees-C converts 1 to the trimer [H2AlPMes2]3(3);further heating at 125-degrees-C results in the formation of Mes2PH and aluminum metal.
