摘　　要：A series of chiral and achiral bis(2-oxazolinylphenolato)nickel(II) complexes 2 were synthesized by reactions of various 2-(4,5-dihydro-2-oxazolyl)phenol derivatives with nickel chloride hexahydrate. The molecular structure of complex 2a was determined by X-ray single crystal diffraction. The crystal of complex 2a was monoclinic, space group P21 with cell dimension of a=1.1121(4) nm, b=0.9472(3) nm, c=1.4113(5) nm, ==90, =91.450(6), V=1.4861(8) nm3, Z=2, and =0.693 mm—1. In the solid state, the nickel(II) ion was in a square-planar coordination geometry. The catalytic activities of complexes 2 in Baeyer-Villiger reaction with molecular oxygen were investigated.A series of chiral and achiral bis(2-oxazolinylphenolato)nickel(II) complexes 2 were synthesized by reactions of various 2-(4,5-dihydro-2-oxazolyl)phenol derivatives with nickel chloride hexahydrate.
