摘要
1,2,3,4-Tetrakis(6’,7’--dimethyl)benzoxazolyl cyclobutane was obtained by irradiation of E-l,2-bis(6’,7’-dimethyl-1’,3’-benzoxazolyly-2’)-ethene in ethanol with a 450-watt high pressure mercury lamp. Its crystal and molecular structure has been determined by X-ray diffraction method. The crystal is triclinic, space group A with a = 7.008(2), b=9.586(1), c = 13.174(2)A,α= 104.08(1),β= 98.56(2),γ=99.97(2)°,V= 828.4A3, Mr= 636.76, (C40H36N4O4), Z =1, Dx =1.28g/cm3,μ= 0.78 cm-1 and F(OOO)=336.
