摘要：

The new stable divalent germanium, tin and lead heteroleptic species ArO(X)M [Ar = 2,4,6-[Me2NCH2](3) C6H2; X = Cl, M = Ge (1), Sn (2); X = N(SiMe3)(2), M = Ge (3), Sn (4), Pb (5)] were obtained by ligand redistribution reactions between (ArO)(2)M and MCl2 or [(Me3Si)(2)N](2)M, respectively. The coordination behaviour of the o-dimethylamino side chains of the ArO ligand was studied by NMR spectroscopy. 1-4 show the temperature dependence of their NMR spectra. 1 and 2 exhibit a NMN dynamic 'flip-flop' coordination of the o-dimethylamino groups to the metal, while a rigid N --> M <-- N coordination of the two o-dimethylamino groups of the ArO ligand which can be lifted at higher temperatures (56 degrees C for 3, Delta G(not equal) = 68.55 kJ mol(-1)) is observed for 3 and 4. The chemistry of 1-5 is illustrated through their reactions with quinones. (C) 1998 Elsevier Science S.A. All rights reserved.
