Catalytic Synthesis of Substituted Indoles and Quinolines from the Dehydrative C-H Coupling of Arylamines with 1,2- and 1,3-Diols

Autor: Chae S. Yi, Hanbin Lee

Publikováno v: Organometallics. 35(11)

The cationic ruthenium-hydride complex catalyzes the dehydrative C–H coupling reaction of arylamines with 1,2-diols to form the indole products. The analogous coupling of arylamines with 1,3-diols afforded the substituted quinolines. The catalytic
