CO₂ Capture with Silylated Ethanolamines and Piperazines

Invited for this month's cover is the group of Marcus Herbig from the TU Bergakademie in Freiberg. The cover picture shows the reaction of CO₂ with a silyl derivative of the biogenic amine ethanolamine. The role of CO₂ as a contributor to climate change makes "carbon capture" a desirable goal. However, in addition to simply capture CO₂, aminosilanes form silylcarbamates, which represent starting materials for a variety of crucial chemicals. Thus, the entrapped CO₂ represents a useful C₁ building block. The ESF-funded Junior Research Group CO₂-Sil at the TU Bergakademie Freiberg (represented by their Logo and location) pursues that kind of goals. CO₂-Sil studies these key reactions of CO₂ insertion in depth by syntheses, quantum chemical calculations and calorimetric experiments. CO₂ brought to the ground by our method shall be feedstock for various branches in chemistry. Read the full text of their Full Paper at 10.1002/open.201900269.
