Kinetic analysis of the reaction of Me2S3 and n Pr2S3 in varying concentrations of DMF was also carried out (S11-S24 and S192-S193). This analysis revealed the reaction did not adhere to simple zero-, first-, or second-order rate laws. Because the rate law is not first-order or pseudo first-order, mechanisms involving an irreversible, unimolecular generation of an active species can be ruled out.
