  Synthesis, Structures, and Reactivities of Guanidinatozinc Complexes and Their Catalytic Behavior in the Tishchenko Reaction

  摘要：

  Treatment of a secondary amine (pipH, Bz(2)NH, Et2NH) with sequentially diethylzinc and N,N'-dicyclohexylcarbodiimide in hexane has afforded in good yield the new crystalline guanidinatozinc complexes. Each has been X-ray and solution NMR spectrally characterized Three are dimeric (mono)guandinatozinc alkyls two are dinuclear (tris)guanidinatozinc amides, and one is a homoleptic zinc bis(guanidinate). The reactions of dinudear (tris)guanidinatozinc amides with diethylzinc and N,N'-dicyclohexylcarbodihnide in the molar ratios of 1:2:1 led to the dimeric (mono)guandinatozinc alkyls, homoleptic zinc bis(guanidinate) with an equimolar portion of diethylzinc also yielded dimeric (mono)guandinatozinc alkyls. Each of the complexes exhibited good to excellent catalytic activity for the solvent-free Tishchenko reaction under mild conditions.
