Monofunctionalized tridecachlorodiphenyl (2-pyridyl)methyl radicals. Synthesis and spectral analysis
Abstract
Highly chlorinated diphenyl(2-pyridyl)methyl radicals and their α-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 °C). Their ESR, UV–VIS and IR spectra are given.
