Zeng, Jiajun published the artcileA practical access to 1,2-dicarbonyls via oxidation of alkynes catalyzed by gold(I) immobilized on MCM-41, Recommanded Product: 2-(Thiophen-2-yl)quinoxaline, the main research area is dicarbonyl preparation; alkyne oxidation MCM41 anchored diphenylphosphine gold complex; MCM41 anchored diphenylphosphine gold complex catalyst preparation.
The heterogeneous gold(I)-catalyzed oxidation of alkynes was achieved by using 2,3-dichloropyridine N-oxide as oxidant and MCM-41-anchored diphenylphosphine-gold(I) complex [MCM-41-Ph2P-AuNTf2] as the catalyst under mild and acid-free conditions, yielding diverse 1,2-dicarbonyls in good to excellent yields with easy recycling of the gold catalyst. The developed method is applicable to a wide variety of alkynes including internal or terminal alkynes, alkynyl ethers or thioethers and ynamides, and can tolerate a wide range of functional groups.
