Abstract

Abstract Organic compound conversion in the presence of a new class of heterogeneous catalyst is provided. Said new class of heterogeneous catalyst comprises a substrate having a minimum surface area of about 10 m 2 /g and having pores with a minimum pore diameter of about 5 Angstrom Units, said substrate being modified by at least one amine functional member coordinated to a metal function, said amine functional member acting as a bridging member between said substrate and said metal function.
