Dithiocarbene complexes, Cp(CO)/sub 2/Fe(C(SR)SR')/sup +/, are easily prepared by R'SO/sub 3/F alkylation of the dithioester ligand of Cp(CO)/sub 2/FeC(=S)SR. The dimethyl derivative, Cp(CO)/sub 2/Fe(C(SCH/sub 3/)/sub 2/)/sup +/, shows unusual reactivity toward nucleophilic amines to provide a variety of Cp(CO)/sub 2/FeL/sup +/ derivatives. Primary amines produce isocyanide complexes, Cp(CO)/sub 2/Fe(CNR)/sup +/; secondary amines give amino-thiocarbene complexes, Cp(CO)/sub 2/Fe(C(NR/sub 2/)SCH/sub 3/)/sup +/; diamines, amino alcohols, and amino thiols yield complexes with cyclic carbene ligands, Cp(CO)/sub 2/Fe(CY(CH/sub 2/)/sub n/NR')/sup +/, where Y = NH, O, or S. The novel orthothioformate complex Cp(CO)/sub 2/Fe(C(SCH/sub 3/)/sub 3/) is formed as a byproduct in some of the reactions. Spectral properties of the new complexes are discussed.
