Synthesis and characterization of group 13 dichloride (M = Ga, In), dimethyl (M = Al) and cationic methyl aluminum complexes supported by monoanionic NNN-pincer ligands

Abstract

A series of group 13 dichloride species, supported by monoanionic NNN-pincer ligands, LMCl2 (L = 2,5-(iPr2P[double bond, length as m-dash]NAr)2N(C4H2); Ar = 4-iPrC6H4 (LPipp), 2,4,6-Me3C6H2 (LMes), 2,6-iPr2C6H3 (LDipp); M = Ga (1), In (2)), were prepared via the reaction of NaL with MCl3 and characterized by multinuclear NMR spectroscopy, elemental analysis and X-ray crystallography. Related organoaluminum complexes, LAlMe2 (3), were synthesized by addition of AlMe3 to L. Treatment with the Lewis acid B(C6F5)3 afforded well-defined cationic aluminum methyl species, [LAlMe]+[MeB(C6F5)3] (4), which were found to be thermally stable in both solid and solution state for days.
