Abstract :
A reusable PdCl2(NH3)2/cationic 2,20-bipyridyl system was used to catalyze the double
Mizoroki-Heck reaction of aryl iodides with electron-deficient alkenes in water in the absence of
inert gas, giving ,-diarylated carbonyl derivatives in good to excellent yields. The formation
of unsymmetrical ,-diarylated alkenes were also studied by coupling aryl iodides with the
corresponding aryl-substituted ,-unsaturated carbonyl compounds. This water-soluble catalyst
can be swiftly separated from the organic layer using simple extraction for the further reuse, and,
thus, makes it an operationally-simple and environmentally-benign procedure.
