Di-(3methylindolyl)methane Complexes of Aluminum and Gallium Alkyls

by Das, Anirban

Abstract (Summary)
This thesis reports the reactions of aluminum and gallium alkyls with two ligands, di(3-methylindolyl)pyridylmethane (L'H2), and di(3-methylindolyl)(1-methylimidazolyl)methane (L''H2). A series of bidentate complexes HLMR2 (L = L', M = Al, Ga, R = tBu; L = L'', M = Al, R = Me, Et, iBu, tBu; L = L'', M = Ga, R = tBu) and a tridentate complex L'GatBu were synthesized. Stoichiometry plays an important role in reactions of L'H2 and L''H2 with Me3Al and Et3Al, as excess of the aluminum alkyl results in the formation of bimetallic complexes LAl2R4 (L= L', L'' ; R = Me, Et). The previously reported bis-aluminum complex, L'Al2Me4 was characterized by X-ray crystallography. This is the first reported example of a group 13 complex with a bridging ì2–ç1:ç1–N indolyl group. The characterization of the new complexes was carried out by 1H, 13C and 2-dimensional NMR spectroscopy as well as X-ray crystallography
