Electrophilic additions to alkenes. Part II. Kinetics of the reaction of 2,4-dinitrobenzenesulphenyl bromide with cyclohexene in carbon tetrachloride solution
Abstract:The reaction between 2.4-dinitrobenzenesulphenyl bromide and cyclohexene in carbon tetrachloride solution appears to be essentially homogeneous, and polar. Kinetically it is complex, like many electrophilic additions in relatively non-polar solvents, the reaction being first-order in cyclohexene, and above first-oraer in sulphenyl bromide. The rate equation, Initial rate = k," [B] [ArSBr] + k,[B] [ArSBrIZ + k,[B] [ArSBrI3 where B = cyclohexene, is proposed, and the complexity of this equation attributed to so… Show more
