ANOTHER LOOK AT THE PHOTODECHLORINATION OF BROMODAN

Article abstract of DOI:10.1016/S0040-4020(01)89232-2

Contrary to a previous report, there is no solvent-dependent selectivity to either of the double-bond-dechlorinated derivatives when Bromodan is irradiated in hexane or methanol.The 7-dechlorinated derivative formed on photolysis in triethylamine is debrominated on further irradiation. 13C chemical shifts and longe-range C-H coupling constants indicate that the structural assignment of the double-bond-dechlorinated isomers mest be reversed.
