Epoxides are highly used as the intermediates for the production of pharmaceuticals, drug intermediates, food additives, perfumes, agrochemicals and polymers. It is very imperative to develop a greener and a sustainable reaction protocols on the continuing demand of the epoxides. Propylene oxide (PO) is widely used for the production of propylene glycols and polyurethane. It is found to be one of the most significant members of epoxide family and its total production has been reached nearly about 10 million tons per annum [ 1, 2 ]. Hydrogen peroxide (H 2 O 2 ) based process was industrialized in 2008, for the commercial production of PO through EVONIK and it is selectively produced PO with H 2 O as the only by-product [ 3 ]. But, it can be seen that, H 2 O 2 is found to be comparatively expensive and gets decomposition quickly during the chemical reaction and also it is very difficult for the transportation and the search for an improved process are continued. Various transition...
