Recyclable polymer bound Pd(0) phosphine catalyst for effecting sp2 -sp2 and sp2 -sp carbon-carbon coupling reactions in aqueous medium

摘要

Aqueous Heck type coupling reactions between aryl iodides and terminal alkenes or alkynes have been effected in good yields using a recyclable catalyst system that consists of poly(N-isopropyl acrylamide) bound Pd(0) phosphine and an anionic surfactant,potassium lauryl sulphate.
