摘要

Polymer-supported organotin chlorides have been synthesized by suspension copolymerization of organotin-functionalized styrenic monomers using a precipitating porogen. Their activiteis as reducing catalysts have been evaluted in the reducation of bromoadamantane by sodium borohydride. The influence of the length of the spacer arm between the tin atom and the polymer backbone on the activity and the tin leacing of the supported catalyst have been studied. The nature of the alkyl groups (butyl or phenyl) attached on the tin atom plays an improtant role on the stability toward successive reuse of the supported catayst.
