Reactions of cyclomanganated complexes with carbon disulfide: routes to η2-aryldithiocarboxylate-Mn(CO)4 complexes and to the trithiocarbonate complex (μ3-CS3)2Mn4(CO)16

Reaction of cyclomanganated aryl ketones with CS2 proceeds with insertion into the Mn–C bond to give η2-dithiocarboxylato–Mn(CO)4 compounds. With other cyclomanganated substrates such as that from Ph3PS and also with Mn2(CO)10, CS2 gives (μ3-CS3)2Mn4(CO)16 with bridging trithiocarbonate ligands.
