novel Al and Ga coordination compounds 4, 5, 7, and 8 of the type (NON)AlX (NON2– = RNC6H4}2O2–; 4, R = Cy, X = Me; 5, R = C5H9, X = OCH2Ph; 7, R = C6F5, X = Me) and (NON)GaX (NON2– = R2NHC6H4}2O2–; 8, R = C6F5, X = Me) have been synthesized via, in the case of 4, 7, and 8, a methane elimination reaction between the corresponding protio ligands (NON)H2 and MMe3 precursors (M = Al, Ga). The Al alkoxide
