Mechanistic Study of the Manganese-Catalyzed [2 + 2 + 2] Annulation of 1,3-Dicarbonyl Compounds and Terminal Alkynes.

The manganese-catalyzed dehydrative [2 + 2 + 2] annulation reaction of a 1 ,3-dicarbonyl compound and a terminal alkyne provides an efficient and regioselective synthesis of a substituted benzerie derivative, highlighted by the exclusive formation of a p-terphenyl derivative from an aryl acetylene....
