Abstract

An efficient Hiyama cross-coupling of a wide variety of substituted aryl bromides and iodides with arylsilanes has been achieved at 100° C in water through a simple one-pot operation using in situ generated palladium nanoparticles. This reaction is very fast (5min) and has been performed in air under fluoride-free conditions, giving excellent chemoselectivity and high yields.
