Abstract

A recyclable iron/graphite (Fe/Cg) catalyst for the efficient C-S cross-coupling of various iodoarenes with aromatic/­aliphatic thiols has been developed under ligand-free conditions (26 examples, up to 99% yield). The catalyst can be easily recovered and recycled up to seven cycles without loss of activity.
