Abstract
Abstract Insoluble polymer-bound reagents derived from poly(vinylbenzyltriphenylphosphonium salts) have been prepared and used as reagents in organic synthesis. The polymer-supported borohydride was used as reducing agent towards carbonyl compounds. The reaction of polymer-supported thiocyanate and nitrile anions with alkyl halides in hydrocarbon solvents gave good yields of the corresponding alkyl thiocyanates and nitroalkanes, respectively. In addition, polymer-bound carboxylate, phenoxide, and sulfinate anions were used for the synthesis of esters, ethers, and sulfones by reaction with alkyl halides in non-polar solvents.
