The Kinetics and Mechanism of Nucleophilic Addition of Mercaptan to a -Nitrostyrene in Acidic Media () n-Propyl-and tert-Butylmercaptan

[摘要] The rate equations for the nucleophilic addition reactions of n-propyl-and tert-butyl mercaptan to 3,4-methylenedioxy-¥â-nitrostyrene over wide pH range were obtained. From this equations, the rate constants for n-propyl-and tert-butyl mercaptide ions at high pH were obtained numerically as 1.26¡¿108 and 3.98¡¿106 M-2¡¤sec-1, and for n-propyl-and tert-butyl mercaptan at low pH, 7.07¡¿10-3 and 1.5¡¿10-3 M-1¡¤sec-1 respectively.
