An efficient synthesis of Pd nanoparticles in water has been developed using a Fischer carbene complex of tungsten as the reductant and PEG as the capping agent. These Pd nanoparticles efficiently catalyze Hiyama cross-coupling reactions performed in air. Excellent yields of products were obtained with a wide range of substrates.
