Abstract

The present report describes an efficient and simple protocol for phosphine-free Heck reactions in water using a Pd(l-proline)2 complex as the catalyst under controlled microwave irradiation conditions. This methodology is versatile and provides excellent yields of products in short reaction times and minimizes costs, operational hazards and environmental pollution.
