摘要

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 similar reactions of the corresponding chloro-and iodoarenes. In general, photolytic cleavage of the C–X bond of 2, 6-difluorohalo (X) benzene was shown to proceed more easily than the corresponding 2, 4-difluorohalo compound.
