Abstract: The series of new 2‐substituted‐5,7‐di(het)aryl‐6‐nitro‐4,5,6,7‐tetrahydroazolo[1,5‐a]pyrimidines were synthesized by reaction between imine and 1‐substituted 2‐nitroethylene derivatives. The structure of the obtained compounds including stereochemical configuration was confirmed by NMR techniques such as 1H, 13C, 2D 1H‐1H… read more here.

Abstract: Significance Estimating the social cost of carbon (SCC)—the cost of one additional ton of CO2 emitted—is crucial for the analysis of climate change policies. Despite numerous recent studies investigating how fundamental aspects of model structure… read more here.
