The hydrido complexes reacted with MeI to afford the iodo derivatives 1.The reaction of 1 with Na(SEt) led to the terminal thiolato complexes 2.Compounds 2 were used to bind the metal carbonyl fragments Fe(CO)4 and M(CO)5 from and (thf = tetrahydrofuran) respectively.The corresponding monothiolato-bridged complexes n>> 3 (M = Fe, n = 4; M = Mo or W, n = 5) were obtained only in the case of L = CO and no dibridged μ-SEt, μ-Co complex was formed.The new complexes 1-3 were characterized by IR, 1H and 31P NMR spectroscopies.The X-ray analysis of > showed an endo position of the ethyl group with respect to the CO ligand bound to the niobium.The results of extended-Hueckel molecular orbital (EHMO) conformational calculations carried out on the model complexes and are compared, and the importance of electronic and steric effects deduced.An explanation for the non-formation of dibridged μ-SEt, μ-CO complexes is attempted on the basis of EHMO and X-ray results.

The combined utilization of Me2-cAAC (Me2-cAAC =:C(CH2)(CMe2)2N-2,6-iPr2C6H3) and thiolates as supporting ligands enables the access of unprecedented carbene coordinated thiolate-bridged diiron(ii) complexes [(Me2-cAAC)Fe(μ-SR)(Br)]2 (R = Me, 3; R = Et, 4). The coordination environment of each tetrahedral iron(ii) center in complexes 3 and 4 is composed of one terminal bromide atom, one carbene carbon atom and two thiolate sulfur atoms, which is similar to the carbide-containing sulfur-rich environment of iron centers in the belt region of the FeMo-cofactor. Interestingly, when NaSCPh3 was chosen as the thiolate ligand, C-S bond homolysis occurred to form a rare [3:1] site-differentiated cubane-type cluster [(Me2-cAAC)Fe4S4(Br)3][Me2-cAACH] (5). Furthermore, complexes 3 and 4 exhibit good exchange reactivity toward the azide anion to give novel thiolate-bridged diiron complexes with two azido ligands in a trans arrangement.

Paragraph 0075; 0076; 0077, (2014/02/15)
The present invention provides a method for producing a 1,2-benzisothiazol-3-one compound by reacting a 2-(alkylthio)benzonitrile compound with a halogenating agent in the presence of water, wherein an alkyl halide that is generated as by-product is reacted with a sulfide to form an alkylthiol, which is converted into an alkali metal salt, and then the resulting alkali metal salt is reacted with a 2-halobenzonitrile compound to be converted into a 2-(alkylthio)benzonitrile compound and reused as a starting material for the production of a 1,2-benzisothiazol-3-one compound. By means of the present invention, it is possible to efficiently use the by-product that is generated during the production of a 1,2-benzisothiazol-3-one compound and economically produce a 1,2-benzisothiazol-3-one compound without placing a burden on the environment.
