In 2019,Angewandte Chemie, International Edition included an article by Falconnet, Alban; Magre, Marc; Maity, Bholanath; Cavallo, Luigi; Rueping, Magnus. COA of Formula: C6H6OS. The article was titled 《Asymmetric Magnesium-Catalyzed Hydroboration by Metal-Ligand Cooperative Catalysis》. The information in the text is summarized as follows:
Asym. catalysis with readily available, cheap, and nontoxic alk. earth metal catalysts represents a sustainable alternative to conventional synthesis methodologies. In this context, the authors describe the development of a 1st Mg(II)-catalyzed enantioselective hydroboration providing the products with excellent yields and enantioselectivities. NMR spectroscopy studies and DFT calculations provide insights into the reaction mechanism and the origin of the enantioselectivity which can be explained by a metal-ligand cooperative catalysis pathway involving a noninnocent ligand. The experimental process involved the reaction of 1-Thiophen-2-yl-ethanone(cas: 88-15-3COA of Formula: C6H6OS)
1-Thiophen-2-yl-ethanone(cas: 88-15-3) belongs to thiophenes. Specialized thiophenes can be synthesized similarly using Lawesson’s reagent as the sulfidizing agent, or via the Gewald reaction, which involves the condensation of two esters in the presence of elemental sulfur. Another method is the Volhard–Erdmann cyclization. COA of Formula: C6H6OS
