Iron-catalyzed direct alkenylation of sp~3(C-H) bonds via decarboxylation of cinnamic acids under ligand-free conditions

摘要

An example of highly efficient low-cost ferrocene-catalyzed decarboxylase C(sp~2)-C(sp~3) coupling reactions via C-H functionalization has been developed successfully. It is noteworthy that nanoparticles of Fe3O4 could be used as a reusable catalyst for 7 times in the absence of ligand.
