Reported herein is a well-defined bidentate geometry-constrained iminopyridyl Co complex for an efficient and highly Markovnikov-selective hydrosilylation of alkynes, featuring a broad substrate scope including aromatic/heteroaromatic/aliphatic alkynes and primary/secondary silanes. TON is up to 4950. The kinetic study together with structures clearly revealed that the ligand played the key effect on the efficiency. In the experiment, the researchers used many compounds, for example, 2-(But-3-yn-1-yloxy)tetrahydro-2H-pyran (cas: 40365-61-5Application of 40365-61-5).
2-(But-3-yn-1-yloxy)tetrahydro-2H-pyran (cas: 40365-61-5) belongs to tetrahydropyran derivatives. Tetrahydropyran is a useful synthetic intermediate. Tetrahydropyranyl (THP-) ethers derived from the reaction of alcohols and dihydropyran are common intermediates in organic synthesis. 2-(Arylmethylene)cyclopropylcarbinols could be converted to the corresponding tetrahydropyrans stereoselectively in the presence of Brønsted acids under mild conditions. A plausible Prins-type reaction mechanism has been proposed.Application of 40365-61-5
