olefins of the type XCH=CHY, where Y is an electron-withdrawing group and X is a good leaving group, can undergo nucleophilic vinylic substitution reactions by a single-step or a multistep addition–elimination mechanism, depending on the chemical structure of the olefin and the reaction ...

The reaction is best explained by an elimination-addition mechanism with 4-substituted cyclohexyne as a common intermediate. The cyclohexyne formation was confirmed by deuterium labeling and trapping to lead to [4 + 2] cycloadducts and a platinum-cyclohexyne complex. Cyclohexyne can also be ...

From a study of the pH-exchange rate profile and other data, it is shown that two mechanisms are important in the substitution of deuterium for hydrogen at C 2 in thiazole in deuterio-hydroxylic solvents. These pathways are a simple base-induced proton abstraction which is important at high...
