A photoredox strategy for the synthesis of a wide range of allylic amines and ethers from carboxylic acids and alkynes has been developed. This approach relies on the perturbation of the ground-state electronic properties of terminal alkynes through the formation and photoexcitation of copper acetylide intermediates. This process takes place through cooperative copper and organic photoredox catalysis and can be carried out in a stereodivergent manner. Thus, a systematic multivariate HTE screening spotlighted that a switch in the stereochem. outcome can be provoked by choosing an appropriate combination of ligand and base. The developed methodol. has been applied to the stereoselective coupling of primary, secondary, and tertiary alkyl radicals with (hetero)aromatic terminal alkynes. As an addnl. practicality, similar reaction conditions allowed for the use of aromatic amines as radical precursors in a cross dehydrogenative coupling for the direct vinylation of inactivated C-H bonds. In the experiment, the researchers used 4-Ethynylpyridine(cas: 2510-22-7Recommanded Product: 2510-22-7)
4-Ethynylpyridine(cas: 2510-22-7) belongs to pyridine. Pyridine is widely used in the precursor to agrochemicals and pharmaceuticals. Also, it is used as an important reagent and organic solvent.Recommanded Product: 2510-22-7
