Latent Ruthenium Catalysts for Ring Opening Metathesis Polymerization ROMP

Latent Ruthenium Catalysts for Ring Opening Metathesis Polymerization (ROMP) 

For over two decades, the development of olefin metathesis by many research groups has yielded more stable catalysts with higher turnover frequencies and greater substrate range. Modern olefin metathesis reactions are catalyzed by well-defined complexes of transition metals, such as ruthenium, tungsten, and molybdenum. In these complexes, the metal atom is naturally surrounded by carefully chosen ligands, which provide the desired electronic and steric environment to the metal. 

Olefin metathesis has evolved to become one of the most useful methods for the polymerization of olefins, because it allows the construction of well-defined macromolecules, with high functional group tolerance and exquisite morphological control [1-3]. 

In this chapter we will cover the recent uses of latent initiators for ROMP reactions. The first part of the chapter will deal with two physical methods of activation thermal and Ught-activated ROMP. Then we will continue to chemically
