Herein, we report the stereoselective synthesis of (1 + n)-membered cycloalkane from Me ketone and 1,n-diol. A manganese(I) complex bearing a phosphine-free ligand catalyzed the reaction, which involved the formation of two C-C bonds via a sequence of intermol.- and intramol.-borrowing hydrogenation reactions. It produces 2 mol of water as the sole byproduct, making the process atom economical and environmentally benign. Multisubstituted cycloalkanes were obtained in good to excellent yields with very high selectivities. A thorough mechanistic anal. by high-level DFT computation rationalizes the choice of the pincer and establishes the role of hemilability of the ligand for this efficient transformation. In the part of experimental materials, we found many familiar compounds, such as 1-Thiophen-2-yl-ethanone(cas: 88-15-3Recommanded Product: 88-15-3)
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. Recommanded Product: 88-15-3
