A convenient and useful method of preparation of alpha-bromo enones from the corresponding enones using organic ammonium tribromide (OATB)

Various acyclic a-bromo enones 2 as well as cyclic alpha -bromo enones 4 can be prepared from the corresponding acyclic enones 1 and cyclic enones 3 respectively, in a one-pot procedure by employing organic ammonium tribromide, such as cetyltrimethylammonium tribromide (CetTMATB) or tetrabutylammoni...

Summary:Various acyclic a-bromo enones 2 as well as cyclic alpha -bromo enones 4 can be prepared from the corresponding acyclic enones 1 and cyclic enones 3 respectively, in a one-pot procedure by employing organic ammonium tribromide, such as cetyltrimethylammonium tribromide (CetTMATB) or tetrabutylammonium tribromide (TBATB) in presence of K2CO3 in dichloromethane at 0 degreesC to room temperature under very mild conditions in good yields(2).
