CONCURRENT CATALYTIC REDUCTION STOICHIOMETRIC OXIDATION USING OLIGOMERICALLY LIGATED CATALYSTS AND POLYMER-BOUND REAGENTS Academic Article uri icon

abstract

  • In this paper we describe procedures using macromolecular reagents which permit the simultaneous use of otherwise incompatible reagents and the recovery and separation of each individual reagent, catalyst, or reaction product. Numerous literature examples describe the advantageous use of the physiochemical properties of insoluble macromolecular reagents in synthetic, mechanistic, and catalytic studies.1Included among these examples are cases in which the insolubility of two separate polymeric reagents or catalysts is used to permit use of mutually self-destructive species.2,3Here we describe a different approach to separation of two mutually incompatible species in which the size of a soluble macromolecular reagent is used to keep a catalyst and reagent apart. Our strategy allows simultaneous reactions to be carried out with incompatible reagents or catalysts and allows separate recovery and isolation of each reagent, catalyst, or product. Specifically, we describe a rhodium hydrogenation catalyst ligated by diphenylphosphinated ethylene oligomers which can be used as a homogeneous catalyst to effect alkene reduction of a substrate which is at the same time being oxidized by an insoluble poly(vinylpyridine)-bound Cr(VI) oxidant. 1985, American Chemical Society.
