3,4-Diphenyl-1,2,5-thiadiazole 1-oxide (1a) in acetonitrile solution is electroreduced to 2,4,6-triphenyl-1,3,5triazine and 3,4-diphenyl-1,2,5-thiadiazole. This behavior is very different from that of similar compounds with other oxidation states of the heterocyclic sulfur atom, such as the 1,1-diox

We have performed a product and kinetic study of the hydrolysis of 3,4-diphenyl-1,2,5-thiadiazole-1,l-dioxide in aqueous solution. Benzil and sulfamide are the only products of hydrolysis and are formed in equimolar yields. The kinetic results indicate that a first order law is followed up to 90% c
Ah&met-The equilibrium between I and the product restthing from the addition of ethanol to one of its C-N double bonds: 3-ethoxy-3,4-diphenyl-lJ,Qhiadisxohne 1,ldioxide (II), is studied by electrochemical methods in ethanol (EtOH)-acetonitrile (ACN) solvent mixtures. The equilibrium constant is meas
