A NOVEL SYNTHETIC METHOD AND STRUCTURE OF TETRAKIS(BENZOATE)BIS(TRIPHENYLPHOSPHINE OXIDE)DICOPPER(II).OXIDATIVE ADDITION OF DIBENZOYL ON METALLIC COPPER

摘要

Dibenzoyl peroxide undergoes oxidative addition on metalliccopper with triphenylphosphine in a mixed solvent（acetone,dichloromethaneand trichloromethane）,and affords the binuclear copper complex（Cu（C₆H₅COO）₂（OPPh₃））₂.Crystals are monoclinic,space group A₂/a,withcell parameters,a=24.337（3）,b=10.566（1）,c=21.579（2）,β= 93.18（1）°,V=5540（1）3,Z=4,R=0.042,and Rw=0.044 for 5872 observed reflections.Each copper ion is coordinated by four bridging benzoato ligands and onetriphenylphosphine oxide group to form binuclear complexes.
