A recyclable perfluoroalkylated PCP pincer palladium complex

摘要

A new fluorous PCP pincer ligand has been coordinated to Ni(ii), Pd(ii) and Pt(ii). The air stable palladium complex, which promotes Heck reactions between methyl acrylate and either aryl bromides or iodides, can be recovered intact by fluorous solid-phase extraction and was reused four times in the Heck reaction between methyl acrylate and 4-bromoacetophenone without loss in catalytic activity.
