ABSTRACT OF THE DISCLOSURE ORGANOMETALLIC COMPLEXES AND THE USE THEREOF IN EXPOXIDATION OF OLEFINS A family of polymer bound organometallic complexes comprises compounds derived from a metal and a functionalised organic polymer of formula Image wherein X is a polymer backbone bonded to a ligand in which;Y is a group derived from an atom selected from C, Si, N and P; R1, R2, R3 and R4 are, independently, groups selected from H, a C1-C4 alkyl group and a halogen atom; R5 and R6 are, independently, groups selected from H, a C1-C4 alkyl group and a halogen atom, or together with the nitrogen atom form a heterocyclic ring having 5 or 6 atoms; R7 and R8 are, independently, groups selected from H, a C1-C4 alkyl group, an aryl group and a halogen atom and each of n and m have a value from 0 to 10. When the metal is either molybdenum or vanadium the complexes are suitable catalysts for the epoxidation of olefins.
