A team from the Klausen, Johnson, Craig, and Kulik labs report the geometrically selective synthesis of trans- and cis-silacycloheptenes via a novel synthetic strategy and probe the effect of Si for C substitution on ring-opening metathesis polymerization (ROMP). The results point to the possibility of employing Si-rich polymers to prove the contribution of strand elasticity to the mechanical properties of bulk polymer networks.
