The I–-, Br–-, and Cl–-promoted dehalogenations of several meso- or erythro-1,2-dibromo-1-(4-R1-phenyl)-2-(4-R2-phenyl)ethanes and the I–- and Br–-promoted dehalogenations of erythro-1-bromo-2-chloro-1,2-di-phenylethane have been investigated. The reactions with I– have been carried out in MeOH and dimethylformamide, those with Br– and Cl– in dimethylformamide. Both leaving-group and substituent effects
