An alcoholic solution of nickel chloride, when treated with an ethereal solution of dithiobenzoic acid, CeHsCSSH, blue nickel(II) dithiobenzoate, (C6H5CSS)2Ni, is formed ... 

Dithiobenzoic acid is reported to react with sulfur dichloride to give a compound C7H5S3CI which was suggested to be 4-phenyltrithietanylium chloride (Scheme 139). The reaction of the latter with aniline gives sulfur and thiobenzanilide (68JHC141). 

Dithiobenzoic acid, PhCSSH, and dithiophenylacetic acid, PhCH CSSH, form low-spin monomeric square-planar [MnL2] (Mu = Ni, Pd, Pt) and octahedral (MUI = Cr, Co, Rh, In)...

Thiobenzophenone and thiofluorenone are readily transformed with xenon difluoride in to difluoro products90, thiobenzoic acid to benzoyl fluoride90 and dithiobenzoic acid to trifluoromethylbenzene114 (Scheme 47). 

The reaction pathway has been rationalized in terms of an attack of the triplet oxygen at the 5-position of (76) to produce the diradical (77) which may add to a second molecule of (76). The resulting peroxide (78) fragments to the dithiobenzoic acid derivative (79) which may act as a dipolarophile in the last step of the [3 + 2] cycloaddition reaction of (76). The structure of the final product (80) was established by X-ray analysis (81CB285). 

Tellurium Dithiobenzoate Chloride1 A solution of 0.11 g (0.7 mmol) of freshly prepared dithiobenzoic acid in 30 ml of hexane is added to a suspension of 0.27 g (1.0 mmol) of tellurium tetrachloride in hexane. The temperature of the reaction mixture is held at — 70° and the mixture is stirred for 30 min. The mixture is then filtered, the solid is washed with four 5 ml portions of hexane and then with three 10 ml portions of diethyl ether yield 54 mg (37%) m.p, 195° (dec.). 

The macrocyclic thiaether-esters 84, 85, and 86 were prepared by the reaction of 2,2 -dithiobenzoic acid dichloride with corresponding diols in 31%, 80%, and 85% yields, respectively <2005PS1953>. The complexation abilities of these thiaether-esters toward Li+, Na+, K+, Mg2+, Ca2+, Sr2+, Ba2+, Co2+, and Ni2+ were measured by the solvent extraction experiments. The results showed that 84 exhibits stronger selectivity toward Li+, 85 toward Ba2+, and 86 toward K+. 

In the reaction of substituted dithiobenzoic acids 555 with DCC, stable dithioacyl sulfides 556 are isolated in 75-85 % yield. ... 

Thiobenzoylthioglycolic acid has been prepared by the interaction of potassium dithlobenzoate and alkali chloroacetate. " The required intermediate, dithiobenzoic acid, has been obtained from phenylmagnesium bromide and carbon disulfide, -or by the condensation of benzaldehyde and hydrogen polysulfides, or most conveniently by treatment of benzotrichloride with potassium hydrogen sulfide. - The last procedure has been adapted here to afford improved yields. 

A 1,2,3-trithietane has been suggested as an intermediate in the exchange with sulfur-35 of the thiourea sulfur atom of the histamine receptor antagonist, metiamide a cationic 1,2,3-trithietane was suggested as the product of the reaction of sulfur dichloride with dithiobenzoic acid,p-methoxydithiobenzoic acid, and a-dithionaphthoic acid. ... 

ZnnL2 and NinL2 complexes of the para-substituted dithiobenzoic acid (C (III2 OC6II4CS2 ) make unusual liquid crystals—metal mcsogcns, which are phases that act as self-contained, nonpolar support phases that substrates can diffuse into and out of. Ni"L2 s separate polyaromatic hydrocarbons (PAFfs) and phenols, whereas ZnnL2 s separate R2S and phenol substrates.50,51... 

The molecular structures and intramolecular hydrogen bonding for salicylic (I), 2-hydroxythiobenzoic (II), 2-hydroxythionobenzoic (III) and 2-hydroxy-dithiobenzoic acids (IV) were studied precisely by ab initio method and density functional theory. The carbonyl electrical field-gradient (EFG) tensor and chemical shift (CS) tensor of a urea-type functional group, R NH-C(0)-NHR were determined. Quantum chemical calculations revealed very large... 

Reaction of the piperidinium salt of the dithiobenzoic acid (260) with equimolar amounts of chloroacetaldehyde as its sodium hydrogensulfite adduct (261) followed by an acid-catalyzed cycli-zation gives access to 2-phenyl-1,3-dithiolylium tetraphenylborate (262) (Equation (44)) <75S277>. 

Reaction of 62 with dithiobenzoic acid 608 in 50% methanol containing sodium hydroxide gave 609 by a manner analogous to the reaction leading to compound 607 in Scheme 179. The yield of 613 was very low (18%) (81JCS(P1)2948) (Scheme 180). 

Preparation. Several methods of preparation have been reported, but the most convenient is probably the reaction of CS with phenylmagnesium bromide or phenyllithium to give dithiobenzoic acid this is converted into thiobenzoyl chloride with thionyl chloride. Oxygen must be rigorously excluded or benzoyl chloride is formed. The reagent reacts with alcohols in dry pyridine to... 

Dithiobenzoic acid reacts with equimolar amounts of 2,2 -dithiobis(benzo-thiazole) 23 and triphenylphosphine to give 2-benzothiazolyl dithiobenzoate 24 in good yields (Scheme 14) [43]. The product 24 is an effective thiobenzoyla-tion reagent in reactions with amines or alcohols.
