The cobalt phenylthiolate complex, cis,mer-(PMe3)3Co(CH3)2SPh, was found to undergo competitive two-electron ethane reductive elimination and C-H bond cyclometallation. The thiophenolato bound cobaltacycle was generated via C-H bond oxidative addition to a five-coordinate intermediate followed by rapid methane elimination. A related cobalt isothiocyanate complex, cis,mer-(PMe3)3Co(CH3)2NCS, was also prepared and found to perform ethane elimination and S-atom transfer to yield trimethylphosphine sulfide. This rare example of S-atom donation from a isothiocyanate was characterized by NMR and GC-MS analysis, with cis,mer-(PMe3)3Co(CH3)2CN identified as one of the cobalt based products. This journal is

The novel hydridocobalt(III) complex [mer-Co(H)(SPh)2(PMe3)3] (1) was prepared by reaction of thiophenol with [Co(PMe3)3Cl], [Co(PMe3)4] and [Co(PMe3)4Me]. A dinuclear cobalt dithiophenolato complex [Co(PMe3)2(SPh)]2 (2) was obtained from the reaction of thiophenol with [Co(PMe3)4Me]. Reaction of 1 with iodomethane afforded complex [Co(PMe3)3(I)2] (3). Reaction of complex 2 with carbon monoxide gave a mononuclear dicarbonyl cobalt(I) complex [Co(PMe3)3(CO)2(SPh)] (4). The crystal structures of 1-4 were determined by X-ray diffraction. Formation mechanism of 1 is discussed.
