The term “organocatalysis” or organic catalysis describes the acceleration of chemical reactions through the addition of a sub-stoichiometric quantity of an organic compound. The interest in this field has increased spectacularly in the last few years as result of both the novelty of the concept and, more importantly, the fact that the efficiency and selectivity of many organocatalytic reactions meet the standards of established organic reactions. Organocatalytic reactions are becoming powerful tools in the construction of complex molecular skeletons. The diverse state-of-the-art examples show that in recent years organocatalysis has developed within organic chemistry into its own subdiscipline, whose “Golden Age” has already dawned.

Organic catalysis in ring-opening polymerization (ROP) has become a powerful alternative to more traditional metal-based catalysts. The field has developed to a point at which there are not only excellent low cost and easy to use organocatalysts for day-to-day polymerizations, but the ability to precisely control the synthesis of advanced polymer architectures and ROP monomers that are extremely challenging to polymerize with other catalysts now exists.

This viewpoint presentation will highlight and exhibit the key advances in organocatalyst designed in the SMPC lab with the aim of encouraging the wider application of organic catalysts in ROP. Will be discussed old or totally new organocatalysts which allowed on the preparation of new polymeric material structures.
