Molecular Structure of 4,4′-Dimethoxydibenzoyl Peroxide
Bulletin of the Academy of Sciences of the USSR, Division of Chemical Science
An x-ray diffraction structural analysis gave the geometrical parameters of 4,4′-dimethoxydibenzoyl peroxide and dibenzoyl peroxide. The Raman spectra were also taken for these two peroxides. The introduction of electron-donor substituents into dibenzoyl peroxide causes a decrease in the COOC dihedral angle, νC=O frequency and strength, of the O-O bond with retention of the O-O and C=O bond lengths within experimental error.
