tetrahydrofuran) with bi- and trivalent metal alkoxides [M(OtBu)x]n (M = Ge, Sn; x = 2; n = 2; M = Pb, x = 2; n = 3; M = Al, Fe; x = 3; n = 2) resulted in volatile products of the general formula MCe(OtBu)4+x (M = Al (4), Fe (5); x = 3; M = Ge (8), Sn (9), Pb (10); x = 2) in high yields. By dissolving 4 and 5 in pyridine the solvent adducts MCe(OtBu)7(NC5H5) (M = Al (6), Fe (7)) were formed, whereas 8 and 9 reacted
