Question

Which of the following reactions can be used for the synthesis of an alkene? (A) Chugaev reaction (B) Dakin reaction (C) Reimer-Tiemann reaction (D) Wurtz-Fittig reaction

Tardigrade Admin · Accepted Answer

Dehydration of primary alcohols with alkoxide and CS 2 to give terminal alkenes is called chugaev 'elimination. During this reaction xanthate is formed as intermediate which finally on pyrolysis gives olefin, COS and the thiol. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/bd9a5e96dc737dd625527eeb2870044a-.png" />
