We describe an isomerization-alternating ROMP protocol that gives linear copolymers with rigorous sequence alternation. Bicyclo[4.2.0]oct-7-ene-7-carboxamides of primary amines are isomerized in the presence of (3-BrPyr)<sub>2</sub>Cl<sub>2</sub>(H<sub>2</sub>IMes)Ru=CHPh to the corresponding bicyclo[4.2.0]oct-1(8)-ene-8-carboxamides in which the olefinic bond is tetrasubstituted. The <i>isomerized</i> amides undergo alternating ring-opening metathesis polymerization with cyclohexene to provide ...[more]
