Olefin metathesis provides a versatile synthetic method to produce small, medium and large molecules. Over the past two decades, wide ranges of the molecules have been prepared by various types of olefin metathesis, such as cross metathesis (CM), ring-closing metathesis (RCM), ring-opening metathesis (ROM) reactions. For polymerization, simple polymerization using one of three mechanisms has been a dominant method to produce polymers with rather simple structures. This is because combining more than two different methods into one polymerization fails to give polymers with well-defined structures due to lack of selectivity or control. Here, we demonstrate our recent efforts for developing polymerization methodologies to promote cascade or tandem reactions. This allows us to prepare polymers with more complex structures but still with great selectivity and control. Also, we demonstrate how lessons from organic chemistry can work to improve polymerization. |
