Highly chlorinated diphenyl(2-pyridyl)methyl radicals and their alpha-H precursors with a carboxy, chlorocarbonyl, or allyloxycarbonyl substituent in the 4-position of one phenyl ring have been synthesized. All of them are stable red solids, completely dissociated (magnetic susceptibility), decomposing when melting (200-240-degrees-C). Their ESR, UV-VIS and IR spectra are given.
