摘要

Abstract: 6-Heptyn-2-yl tosylate and 6-octyn-2-yl tosylate were prepared and solvolyzed. Analysis of the reaction rates and of the products agreed in showing that tripie-bond participation occurred in competition with normal solvolysis, and that the proportion of reaction occurring via a participation path increased as the solvent was varied in the sequence acetic acid, formic acid, and trifluoroacetic acid. 6-Octyn-2-yl tosylate did not ...
