Application of Manganese Oxide Octahedral Molecular Sieves(OMS-2)in Clean Synthesis of Organic Compounds

Abstract

： The manganese oxide octahedral molecular sieve ( O M S -2) , because of its excellent oxidation , adsorp tion , ion - exchange , and conductivity properties , was wildly used in various fields such as environmental , semicon ­ ductor , synthetic organic . Because of the mixed valency in the framework and abundant surface defect vacancy , O M S -2 could effectively activate green oxidants such as oxygen and hydrogen peroxide , making it an effective heter ­ ogeneous catalyst and functional supporterin clean synthesis of organic molecules . Moreover , the O M S -2 catalysis material exhiliited excellent activity , selectivity , and structural stability . W e reviewed O M S -2 as heterogeneous cat ­ alyst and electron transfer medium (also as functional supporter in supported catalysts ) in the clean oxidation syn ­ thesis of organic molecules . Finally , the existing problems and future development of O M S -2 -catalyzed oxidations were
