Selective Ozidation of Toluene Catalyzed by M(Ⅱ/Ⅲ) Complezes
(0) 1.Introduction The selective oxidation of hydrocarbons catalyzed by transition-metal complexes is as an important objective in the synthetic chemistry because the discovery of fundamental new selective routes from hydrocarbons to more valuable products (such as alcohols, ketones, acids and peroxides) is necessary1. Furthermore, because of the considerable pressure to replace old technologies with more efficient and sustainable alternatives, H2O2 and O2 are among the most important oxidants for large-scale industrial applications. Nonheme dioxygenases, such as methane monooxygenase and Rieske dioxygenase and tyrosinase, catalyze such reactions and have inspired the development of the alkane oxidation catalysts2,3. Among those mimic complexes, the metal (Ⅱ/Ⅲ) complexes with Di(picolyl) amine derivatives were found as good models to evaluate the structure, spectroscopic features and reactivity of nonheme dioxygenase 4,5. Herein we report the selective oxidation of toluene catalyzed by M-complexes (M=Cu(Ⅱ), (1); Mn(Ⅱ), (2); Fe(Ⅲ) (3)) of bis(pyridine-2-ylmcthyl)-benzylamine) (Phdpa).
