Abstract

The stoichiometric reactions of N-(2-methylquinolin-8-yl)(R) amides (L1–L8; L1, R= Ph; L2, R= p-FPh; L3, R= p-ClPh; L4, R= p-(MeO) Ph; L5, R= o-MePh; L6, R= p-MePh; L7, R= Me; L8, R= CF3) with Me3Al afforded the corresponding dimethylaluminum amidate complexes [Me2Al L](C1–C8). The treatment of N-(2-methylquinolin-8-yl) picolinamide (L9) with 1 or 2 equiv of Me3Al formed Me2Al L9 (C9) or Me2Al L9· Me3Al (C10), respectively; meanwhile, ...
