The relevance of the chemistry of metal-benzenethiolate complexes derives mainly from the apparent importance of metal-cysteinyl sulfur coordination in certain metalloenzymes. The complexes presented herein belong to the class of monomeric [ML4]2 tetrahedral complexes. 

The syntheses of the metal-benzenethiolate complexes are accomplished by a ligand substitution reaction between the appropriate O-ethyl dithiocarbonate complexes and potassium benzenethiolate, KSPh. In the original report on the syntheses of the [M(SPh)4]2 complexes,1 the bis(3,4-dimercapto-cyclobutane-1,2-dione) [dithiosquaric acid] metal complexes were used in the ligand substitution reactions. The rather involved synthesis of the dithiosquarate ligand,2 using expensive starting materials, prompted us to develop new synthetic procedures which utilize the readily available, inexpensive O-ethyl dithiocarbonate complexes.3...

In the gas phase there is no solvent to aid the removal of the proton, and simple addition of the benzenethiol occurs producing one coordinate, and then two coordinate silver complex ions. 

The reaction of (308) with thiophenols gives [TcO(SPh)4] (89) in better yields than by direct reaction with [TcOCy . With the sterically more crowded 2,3,5,6-tetramethyl-benzenethiol (Htmbt, (314)), the Tc-organoimido core is retained and the complex [Tc(NPh)(tmbt)4] is formed and can be identified by mass spectrometry. Reaction with P(CgH4-2-SH)3 (H3PS3, (315)) gives the five-coordinate Tc complex [Tc(PS3)(PPh3)] (316)." ...

Bicyclobutanes as a structural subunit of complex hydrocarbon frameworks also undergo radical addition reactions with benzenethiol and bromotrichloromethane. In compounds such as 23, where the azo functionality can also be involved in a radical reaction, a half-cage compound 24 was produced in 64% yield.38 The generation of other half-cage compounds from 23 and its analogs are shown in Table 10.38...

Dithioalkoxo- and dithiophenoxo-niobium(V) trichlorides [MCl3(SR)2] were obtained from NbCl5 and thiols and benzenethiol respectively.240 The synthesis of tris(benzenedithiolato) complexes was accomplished by reaction of the appropriate metal amide with a mixture of the dithiol and its sodium salt in THF. The structures of (AsPh4)[M(S2C6H4)3]241""243 showed the... 

Organosulfur compounds such as alkene- and arine-thiols apparently stabilize nickel-sulfur bonds as indicated by the complexes which were reported to have mercaptans as unique ligands. The tetrahedral tetrakis adduct with benzenethiolate, (Ph4P)2[Ni(SPh)4] (267 /weB =...
