Abstract
Photolyses of 2,6- and 2,4-difluorobromobenzenes in acetonitrile gave isomerized and brominated products in addition to 1,3-difluorobenzene produced by the dehalogenation. The reactions were compared with simil ar reactions of the corresponding chloro-and iodoarenes. In general, p hotolytic cleavage of the C-X bond of 2,6-difluorohalo(X)benzene was s hown to proceed more easily than the corresponding 2,4-diffuorohalo co mpound.
