外文摘要：The construction of heterogeneous frustrated Lewis pairs(FLPs)catalysts is crucial for realizing highly efficient and recyclable pyridines catalytic hydrogenation.In this work,we prepared a recyclable heterogenous FLPs catalyst CMP-BF with conjugated microporous polymer CMP-ethynyl as the support via self-catalyzed 1,1-carboboration reaction with commercial Lewis acid B(C6F5)3.The as-synthesized CMP-BF demonstrates superior heterogenous catalytic hydrogenation performance(conversion＞99％),and considerable stability(84％conversion after three cycles)in recyclable hydrogenation of 2,6-phenylpyridine.This work provides insights into the fabrication and catalytic application of recyclable heterogenous FLP catalysts.
