Rhodium PC carbene P complexes 1‐L {L=PPh 3 , PPh 2 (C 6 F 5 )} react with isothiocyanate, carbodiimide and disulphide to enable C−S, C−N and S−S bond cleavage. The cleaved molecules are sequestered by the metal center and the pincer alkylidene linkage, forming η 2 ‐coordinated sulfide or imide centered pincer complexes. When a C−S or S−S bond is cleaved, the resulting complexes can bridge two rhodium centers through sulphur forming dimeric complexes and eliminating a monodentate phosphine ligand.
