Abstract
AbstractA series of chiral and achiral bis(2‐oxazolinylphenolato)nickel@) complexes 2 were synthesized by reactions of various 2‐(4, 5dihydro‐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, α=γ=90°,β=91. 450(6)°, V=1.4861(8) nm3, Z=2, and μ=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.
