An intramolecularly base-stabilized monomeric organoaluminum dihydride

The intramolecularly base-stabilized arylaluminum dihydride [2,6-(Me2NCH2)2C6H3]AlH2 (1) has been prepared by the metathesis reaction of the corresponding lithium aryl with AlH2Cl·NMe3. Alternative methods for the synthesis of 1 are transmetalation or reduction reactions of [2,6-(Me2NCH2)2C6H3]MCl2 (M = Al (2), Ga (3), In (4)) with LiAlH4. The x-ray crystal structures of 1 and 2 have been determined: 1, orthorhobic, Pbca, with a = 17.179(3), b = 9.014(20, c = 12.707(3) A ̊, V = 2794(1) A ̊3 and Z = 8; 2, monoclinic, C2 c, with a = 8.2880(10), b = 17.022(2), c = 14.381(3) A ̊, β = 99.46(1)°, V = 2001.2(5) A ̊3, and Z = 4. Compounds 1 and 2 are monomeric in the solid state. © 1995.
