The reaction rates of 2-chloro-3,5-dinitropyridine 1 with a series of arylthiolates 2a-h in methanol have been measured at 25ยฐC. The products are the corresponding 2-thioaryl-3,5-dinitropyridine 3a-h. Good Hammett correlation with value ฯช1.19 was obtained suggesting an elimination-addition mechanism
The rate of the solvent substitution reaction, CoCl 3 S ร +Cl ร YCoCl 4 2ร +S (S-solvent) has been studied by means of stopped flow spectrophotometry in dimethyl sulfoxide (DMSO) and N,N-dimethylformamide (DMF), and the rate constant k f , and the activation enthalpy D f H p and entropy D f S p have
