Carbon dioxide and related heterocumulenes at zinc and lithium cations: bioinspired reactions and principles

摘要: This Perspective starts with the discussion of properties an interesting metalloenzyme (carbonic anhydrase, CA) that performs extremely successfully activation carbon dioxide. Conclusions from are important for many synthetic procedures and include experimental theoretical investigation (DFT calculations) such metal mediated processes in condensed gas phase which zinc cation plays a dominant role. is extended to bio-analogue further heterocumulenes as COS, atmospheric trace gas, CS2. Novel complexes serve useful catalysts reactions (copolymerisations cyclisation) CO2 oxiranes discussed subject inclusion recently published DFT calculations. We continue very general aspect insertion into metal–nitrogen bonds (formation carbamates). again closely related biological or processes. describe synthesis mechanistic aspects characteristic carbamates wide variety metals aspects, especially formation Mg2+ Li+ cyclic products after addition CO2, Ph-NCO CS2 novel ligands, 4H-pyridin-1-ides finally result e.g. 1,3-thiazole-5(2H)-thiones.
