A series of polymer-supported cooperative PC(sp )P pincer catalysts was synthesized and characterized. Their catalytic activity in the acceptorless dehydrogenative coupling of alcohols and the transfer hydrogenation of aldehydes with formic acid as a hydrogen source was investigated. This comparative study, examining homogeneous and polymer-tethered species, proved that carefully designing a link between the support and the catalytic moiety, which takes into consideration the mechanism underlying the target transformation, might lead to superior heterogeneous catalysis.
合成并表征了一系列聚合物负载协同 PC(sp)P 夹钳催化剂。研究了它们在醇的无接受体脱氢偶联反应和以甲酸为氢源的醛的转移氢化反应中的催化活性。这项比较研究考察了均相和聚合物键合物种，证明了仔细设计支撑物和催化部分之间的连接，考虑到目标转化的基础机制，可能会导致更优越的多相催化。
