The complexes of hypernucleophylic 3-phenyl-4-oxidophenyl-1,2,4-triazol-5-ylidene of chelated type were obtained by the reaction of cyclization of 1-substituted 3-phenyl-4-(2-hydroxyphenyl)-1,2,4-triazolium salts with nickel chloride in the presence of sodium carbonate or potassium tert-butoxide in dimethylsulfoxide. The catalytic properties of the prepared products were studied in the reduction of multiple С=Х bonds and dehalogenation of halogenarenes. Copper (I) carbene complexes proved to be the most active in the reaction of multiple bond reduction, palladium complexes in dehalogenation reaction. It was established that alfa-sultones and sulfonates respectively are formed in the reactions of functionally substituted sulfenes with pyridine N-oxides and aromatic nitriles of alfa-chloroarylaldoximes which can be used for the synthesis of a series of alfa-sultones and sulfonic esters of amidoximes, potential plastificators of rubbers and inhibitors of acidic corrosion of steel.
