摘要

Abstract The ester group exhibits a strong directive effect in the photochemical reduction of a carbon-halogen bond and directs the reduction in perhalogenated chlorofluoropropanoates of the type CFXY-CClZ-COOR (X, Y, Z= Cl, F) to the α-position in the acyl part of an ester. The reduction takes place with the same regioselectivity even in esters CFCl 2-CHCl-COOR (10). In esters containing an α-CCl 2-group the reductions to the first and the second ...
