The 1/1 reaction of Et2Zn with N-t-butyliminopropanone (t-BuNC(H)C(Me)O) leads to quantitative formation of dinuclear [EtZ]2 via ethyl transfer within the unstable Et2Zn(t-BuNC(H)?C(Me)O) complex. An X-ray structure determination has shown the product to have a dinuclear structure involving a N,O-chelate bonded [Et(t-Bu)NC(H)C(Me)O]? mono-anionic ligand and a central four membered Zn2O2 ring formed by intermolecular ZnO coordination. Hydrolysis of this zinc complex gives a quantitative yield of N-t-butyl-N-ethylamino propanone, which upon reaction with Et2Zn reforms the dinuclear zinc complex. 相似文献
