Preparation of a novel homogeneous bimetallic Rhodium/Palladium ionic catalyst and its application for the catalytic hydrogenation of nitrile butadiene rubber

A new hybrid second-generation poly (propylene imine) dendrimer terminated by nitrogen-containing triolefinic macrocycle on the periphery (G2-M) was synthesized. The bimetallic Rhodium (III)/Palladium (II) (Rh3+/Pd2+) dendrimer-stabilized catalysts (G2-M(Rh3+xPd2+10-x)) were prepared by a co-complexation route within G2-M and analyzed by1H NMR, XRD and XPS. The catalytic activity, selectivity and separation capability for the hydrogenation of nitrile-butadiene rubber (NBR) catalyzed by the G2-M(Rh3+xPd2+10?x) have been researched. As a novel catalyst system, the bimetallic ions of Rh3+and Pd2+have influenced on the catalytic activity for the hydrogenation of NBR, which can be related to electron-deficiency effect of Rh3+resulting from the interaction of Rh3+and Pd2+within G2-M.

Preparation of nitrogen-containing 25-membered pentaolefinic macrocycles: (E,E,E,E,E)-1,6,11,16,21-penta(arylsulfonyl)-1,6,11,16,21- pentaazacyclopentacosa-3,8,13,18,23-pentaenes

A stepwise preparation of a series of nitrogen-containing 25-membered pentaolefinic macrocycles is presented. The corresponding arenesulfonamides and trans-1,4-dibromo-2-butene served as precursors for the synthesis. Georg Thieme Verlag Stuttgart.
