Abstract
Novel polymer-supported metal complexes of the formula: PA1 PS --R Me(CO).sub.n H.sub.m where: PA1 PS represents a divinylbenzene crosslinked polystyrene in which the divinylbenzene crosslinking is greater than 1% and less than about 18%; PA1 R represents a cycloalkadienyl radical of 4 through 6 carbon atoms; PA1 Me represents a Group VIII metal; PA1 CO represents a carbonyl radical; PA1 H represents hydrogen; PA1 n represents an integer varying from 0 through 3; PA1 m represents an integer varying from 0 through 2 inclusively with the further provision that 2n+m must total 18 when added to the electrons in R and Me, or n+m must total 0; are prepared by: PA1 brominating PS --H by treating same with bromine in the presence of a thallium salt in a partially or fully halogenated solvent to form PS --Br; PA1 treating said PS --Br so produced with a lithium alkyl of 1 through 12 carbon atoms in an aromatic solvent to produce PS --Li; PA1 substituting said PS-- Li so produced by reaction with a 2-cycloalkenone of 4 to 6 carbon atoms in the presence of an ether solvent and using a water work-up to form a cycloalkenylalcohol-substituted PS ; PA1 dehydrating said alcohol so produced by heat…
