“…However, we adopted a new synthetic strategy, wherein we chose to first prepare the tricyclic skeleton and then introduce a protected dithiolene moiety [39,40]. Starting from 2,3-dichloroquioxaline 12, the tricyclic molecule 13 was prepared in two steps according to a reported method [41]. The enol ether was hydrolyzed to the corresponding enol 14, which was functionalized by bromination to 15 and activated by triflation to give 16.…”

Formate dehydrogenases (FDH) reversibly catalyze the interconversion of CO2 to formate. They belong to the family of molybdenum and tungsten-dependent oxidoreductases. For several decades, scientists have been synthesizing structural and functional model complexes inspired by these enzymes. These studies not only allow for finding certain efficient catalysts but also in some cases to better understand the functioning of the enzymes. However, FDH models for catalytic CO2 reduction are less studied compared to the oxygen atom transfer (OAT) reaction. Herein, we present recent results of structural and functional models of FDH.
