Ring opening metathesis polymerization of bisnorbornene derivatives linked by Cp2Ni2(μ-S)2 bridge

ROMP of 2 with Grubbs I catalyst in CH2Cl2 furnished the corresponding polymer 5 which was characterized by spectroscopic means, particularly, MAS (NMR)-N-13. The EXAFS of 5 results were compared with those of the monomeric starting material 2 and the X-ray data of 2. (c) 2006 Elsevier B.V. All rights reserved.
