Abstract

Carbon disulfide reacts with highly nucleophilic carbonyl monoanions including (η5-dienyl)Fe(CO)2-(dienyl = C5H5, C5H4Me, C5Me5), Mn(CO)4P(C5H11)3- and Re(CO)5- to generate a new class of organometallic compounds which may be called metallodithiocarboxylate anions. Spectral and chemical properties of these thermally unstable anions are discussed including the synthesis of methyl- and triphenylstannyl derivatives which are believed to contain monodentate metallodithiocarboxylate groups. The synthesis of the first well-characterized species containing a bridging monodentate metallodithiocarboxylate group, [C5H5Fe(CO2)2] 2CS2, is described. The latter is also the first example of a metal carbonyl complex in which a carbon disulfide unit is formally inserted into a metal-metal bond.
