Abstract: | The reaction of 4-chloro- and 4-chloro-7-deuteriobenzofurazan with MeS-, isopropyl-S-, and t-Butyl-S- in different alcohols as solvents has been investigated. In going from methanol through isopropanol to t-butanol, a progressive decrease of the contribution of the cine-substitution as compared with the normal substitution pathway has been found. By proceeding in the same order, a decrease of the ratio and -ButylS? has also been observed. |
