A New Ketyl Radical Probe. Dehalogenation ofo-Halobenzophenone

Abstract The reactions of o-, m-, or p-bromobenzophenone and o-iodobenzophenone with various Grignard reagents were carried out in diethyl ether at 0 °C. The product analysis showed that these halobenzophenones can be a good chemical probe to evaluate the electron-transfer ability of nucleophiles to the aromatic ketones.
