The reactions of quadricyclene with p-chlorobenzene- and p-toluenesulfenyl chlorides in methylene chloride were investigated.The reaction of quadricyclene with p-chlorobenzenesulfenyl chloride was studied in media with various polarities.It was shown that the nature of the initial addition products agrees with the previously proposed ion-pair reaction mechanism.When the reaction was realized in acetic acid, the reaction of the initial compounds with the solvent was a competing process.In the absence of lithium perchlorate this reaction became the main process.
Electrophilic cleavage of cyclopropanes. II. Concerning the effect of increasing electron demand upon the product-determining transition state in the reaction of 4-substituted-2-nitrobenzenesulphenyl chlorides and benzenesulphenyl chlorides with tetracyclo2,7.04,6>heptane....

The effect of increasing electron demand upon the product-determining transition state in the reaction of arenesulphenyl chlorides with tetracyclo2,7.04,6>heptane has been investigated.As the electron donating ability of the remote substituents on the phenyl ring of the sulphenyl chloride is varied from nitro to methoxy the relative proportion of adducts derived from edge-on attack is found to increase relative to that of adducts derived from corner attack.An ortho-nitro group was found to lead to a stabilizing interaction only in the case of 2,4-dinitrobenzenesulphenyl chloride.A mechanism involving the competition between the two conceptual modes of approach is suggested.
