those from arylboronic acids. Similar treatment of sodium tetraphenylborate (NaBPh4) with alkenes also affords the corresponding phenylated alkenes in high yields together with biphenyl and benzene as side products. Oxidative addition of a carbonboron bond to palladium(O), formed in situ, to give an organopalladium(II) species is assumed to be the key step of these cross-coupling reactions.
