Rhodium‐catalyzed polymerization goes heavyweight The cover picture shows a neutral rhodium(I) N‐heterocyclic carbene hydrosilylation catalyst immobilized on the surface of MCM‐41. In their Full Paper on p. 1133 ff., F. J. Fernández‐Alvarez, L. A. Oro et al. describe how these rhodium‐containing materials catalyze the preparation of poly(silyl ether)s by hydrosilylation. These results show that the immobilized catalysts provide polymers with higher average molecular weight than those obtained by using the corresponding homogenous systems, which could be attributed to a confinement effect exerted by the channels of MCM‐41.
