Abstract

The use of catalytic amounts of copper iodide and trans-N,N′-dimethylcyclohexane-1,2-diamine in the presence of tetramethylammonium chloride or bromide enables the transformation of easily accessible alkenyl iodides into their far less available chlorinated and brominated derivatives in excellent yields and with full retention of the double bond geometry.
