The commercial success of Heck reaction depends on two main
objectives: (i) the use of cheap starting materials such as aryl bro-
mides and aryl chlorides as the aryl halide source; and (ii) the use
of active and recyclable palladium catalyst that can compensate for
the cost of transition metal [19,20]. In this work, small amount of
palladium are required to perform the reaction of iodobenzene with
several alkenes with high yield and selectivity.
