چکیده	In spite of the importance of the application of allylic C–H bond oxidation of olefins in organic synthesis and existence of the numerous reports, lots of limitations such as large excess of the olefin respect to the oxidant, low chemical yield, long time of reaction and a large amount of the catalyst were reminded. We introduced a novel catalytic system using functionalized MCM-41 as catalyst support to promote efficiency of this reaction. The heterogeneous ligand Pyr-MCM-41 was prepared by substituted 2-aminopyrazine ligand on functionalized MCM-41 with 3-chloropropyltrimthoxysilane and characterized by FT-IR, XRD, SEM, EDX, BET, TGA, CHN techniques. In situ immobilized Pyr-MCM-41 by copper (I) trifluoromethanesulfonate (CuOTf) was applied in direct catalytic esterification of inert C–H bonds in olefins using various peresters at room temperature.
