The kinetics of DMSO (dimethylsulphoxide) assisted one pot cyclocondensation of bisanilino disulphide and 1,3-dicarbonyls has been investigated using spectral method. The kinetic measurements have been carried by varying media, temperature and concentration of the reactants. The assistance of DMSO is investigated. The order of reaction, effects of substituents with dicarbonyls on the rates and thermodynamic parameters has also been reported. First time reaction conditions are optimised for performing the cyclocondensation conveniently and rapidly. Probably mechanism has been proposed and order of reaction was determined on the basis of rate expression and was in agreement with second order rate equation, used for the determination of rate constants.
