eng	Aluminum(III) complexes containing O,O chelating ligand	The stoichiometric reactions of trimethylaluminum with 2,6-(MeOCH2)2C6H3OH (LH) revealed compounds L3Al (1) and L2AlMe (2). On the other hand reaction of 1 equiv. of LH with trimethylaluminum did not lead to the formation of complex LAlMe2 (3), rather 2 together with Me3Al were observed as a result of a disproportionation of 3. Compounds 1 and 2 were characterized by elemental analysis, 1H and 13C NMR spectroscopy and in the case of 1 by X-ray diffraction. Derivative 2 underwent transmetalationwith Ph3SnOH, giving LSnPh3 (4) as the result of amigration of ligand L from the aluminum to the tin atom. The identity of 4 was established by elemental analysis, 1H, 13C and 119Sn NMR spectroscopy and 1H, 119Sn HMBC experiments. The system 2 and B(C6F5)3 in a 1 : 1 molar ratio was shown to be active in the polymerization of propylene oxide and ε-caprolactone.	aluminum;tin;chelating ligands;transmetalation;polymerization
