Thiobenzamide, reduction

Diaryl tellurium arenesufonimides are reduced to the diaryl tellurium by thiourea in acetonitrile solution3, by 1,3-diphenylthiourea in methanol4, by thiobenzamide in methanol4, by thiols in chloroform4, and by diphenyl ditellurium in chloroform5. These reductions proceed in yields of 95%.

MPc modified CPFs have been employed by several researchers for the analysis of thiols. Carbon paste electrodes incorporating OMo (OH)Pc catalyzed the oxidation of cysteine with a considerable reduction in overpotential Table 7.2. The oxidation of cysteine was mediated by Mo Pc species. CoPc modified CPMF was used as a sensor for analysis of cysteine and glutathionine in urine using electrophoresis " , with detection limits of 3.1 x 10 and 3.0x10 M, respectively. CoPc modified CPE was employed for the potentiometric oxidation of 2-mercaptobenzimidazole and 2-mercaptobenzothiazole . Low peak potentials of 0.45 V for the former and 0.27 V for the latter were obtained . A detection limit of 5 x 10 M was obtained. CPFs modified with CoPc showed catalytic activity for the determination of thiocarbonyl compounds (thiourea, thioac-etamide, thiobenzamide, and dithiooxamide) " and the oxidation of thioglyconic acid " . The latter occurred via a two step process, which leads to the formation of the dimer of the thiol " . A carbon paste electrode constructed from NiTSPc immobilized on silica gel modified with 1102 catalyzed the oxidation of cysteine " . The immobilization caused the increase in the monomeric form of the catalysts.
