摘要：
The reaction of [4,6-(MeO)(2)pmNHLi] (pm = 2-pyrimidinyl) with 'ZnCl2' gives the oxo-complex [Zn-4{HN-4,6-(MeO)(2)pm}(6)((4)-O)]. 4thf (1 4thf). containing a tetrahedral arrangement of four Zn centres which surround a central O2- ion, as a result of the presence of lattice hydrolysis of the Zn salt. The bis(primary)amido complex [Zn{HN-4,6-(MeO)(2)pm}(2).TMEDA] (2) is obtained as its toluene solvate (2-toluene) by the reaction of ZnMe2 with 4,6-(MeO)(2)pmNH(2) in the presence of TMEDA (Me2NCH2CH2NMe2). Attempted in situ metallation of the primary phosphide [(MeZnHPBu)-Bu-1](n) using Sb(NMe)(3) gives rise to the trimeric, Me2NH-solvated complex [MeZn(mu-(HPBu)-Bu-1)-NHMe2](3) (3). The solid-state structures of 1, 2 and 3 are reported. Complexes 2 and 3 are the first bis(primary)amido and primary phosphido complexes of Zn. (C) 2003 Elsevier B.V. All rights reserved.
