Two series of aluminum alkyl complexes supported by pyrrolylaldiminate ligands, LAlMe2(1a-7a) and L2AlMe (1b-7b), were successfully synthesized and characterized by NMR spectroscopy and elemental analysis. Reactions of trimethylaluminum with the corresponding pyrrolylaldiminate ligands in the molar...
