enhances the reaction rate but also minimizes the side reactions. This process has a broad substrate scope, mild reaction conditions, good yields, excellent chemo- and regioselectivities, operational simplicity, ease of scale-up and high energy efficiency. In addition, the process is remarkably greener than the previous routes with an atom economy of 70.7%, an E-factor of 1.17 and an eco-scale score of
