The coupling reaction of aryl and vinyl iodides, bromides, and triflates with organostannanes can be effectively conducted using palladium on carbon as a source of Pd0. The yield and rate of reaction are significantly affected by the addition of copper iodide as co-catalyst and triphenylarsine as ligand.

for Heck reactions of arylchlorides and bromides. A sterically and electronically diverse array of aryl bromides, as well as activated arylchlorides, couple with a range of mono- and disubstituted olefins at room temperature, furnishing the arylated product with high E/Z stereoselection. The corresponding reactions of a broad spectrum of electron-neutral and electron-rich arylchlorides proceed at
