Co2(CO)8 reacts with the thioketene (CF3)2CCS to give a dinuclear compound [Co(CO)2(CF3)2CCS]2 (6. Photolysis of (CF3)2CCS with Fe(CO)5 leads to two differing complexes of the type [Fe2(CO)6(CF)3)2CCS] (9 and [Fe(CO)3(CF3)2CCS]2 (10). The “dimeric thiketene” (EtOOC)2CCSSCC(COOEt)2 reacts with Fe(CO)5 to give [Fe2(CO)6(EtOOC)2CCS] (13). The crystal structure of 9 has been determined by X-ray diffraction

The reaction of dicarbonyldicyclopentadienyltitanium, (C5H5)2Ti(CO)2, with bis(trifluormethyl)thioketen, (CF3)2CCS, leads to the complex (C5H5)2Ti[(CF3)2-CCS]2 which contains a TiSCSC rings as confirmed by X-ray structure analysis.
