In the Stille coupling a Pd° or PdII catalyst is used to couple an electrophile (usually a vinyl or aryl bromide, iodide or triflate) with a vinyl or aryl tin compound. Stille couplings can tolerate a variety of functional groups, including alcohols, ketones, enones, esters, lactones, nitriles, nitro groups and epoxides. In couplings with stereochemically defined alkenyl-X or alkenyl-M species, the olefin stereochemistry is retained.
