1-Bromo- and 1-iodo-benzotriazoles
Abstract
1-Bromo- and 1-iodo-benzotriazoles are obtained from 1-chlorobenzotriazole and bromine and iodine respectively. The bromo-compound is a reactive oxidant and source of electrophilic bromine. Pentachlorobenzotriazole is more reactive than 1-chlorobenzotriazole in accord with its greater positive halogen character.
