Sequential Multistep Reactions Catalyzed by Polymer - Anchored Homogeneous Catalysts.
Abstract
The first examples of sequential miltistep organic reactions carried out over polymer-anchored homogeneous catalysts are reported where two such catalysts are bound to the same crosslinked polymer. Also, sequential catalytic reactions where two catalysts, each anchored to a separate resin, are mixed together in the same reactor were conducted. Sequential cyclooligomerization of butadiene to 4-vinylcyclohexene, (Z,Z)-1,5-cyclooctadiene, and (E,E,E)-1,5,9-cyclododecatriene, followed by hydrogenation to ethylcyclohexane, cyclooctane, and cyclododecane, was accomplished using a single styrene-divinylbenzene resin to which (PPh3)2Ni(CO)2 and (PPh3)3RhCl had been anchored. The same reaction sequence was effected by a mixture of two resins to which (PPh3)2Ni(CO)2 and (PPh3)RhCl were individually attached.
