Abstract: In a continuing effort to understand the origins of reactivity in molecularly imprinted polymers, we have developed a program to study the effects of site selective poisoning on the catalytic activity of a polymer immobilized cationic rhodium complex. A polymerizable MeOBiPhep ligand has been synthesized which led to the development of (p-isopropenyl-MeOBiPhep)Rh(cod)+ BF4 (1), a catalyst for the isomerization of allylamines to eneamines. Catalyst 1 was incorporated into a highly crosslinked macroporous EGDMA polymer and has been shown to catalyze the isomerization of N,N-diethylgeranylamine to its corresponding eneamine. A variety of diamines and bisphosphines were then used to poison a portion of the catalyst sites and reaction rates were compared to the corresponding solution experiments. The effect of the steric and electronic properties of the poison on reaction kinetics will be discussed
