Significance
In this communication, Seto and Novak cleverly designed insertion-polymerizable cyclobutenes. These molecules generally are difficult to polymerize in an insertion fashion since they isomerize to butadienes through pericyclic ring-opening reactions. By locking the cyclobutene with a cis-fused ring system, they were able to achieve fairly high-molecular-weight polymers (Mn is up to 155,000) after optimizing conditions.
