A RuH<sub>2</sub>(CO)(PPh<sub>3</sub>)<sub>3</sub>-Catalyzed Regioselective Arylation of Aromatic Ketones with Arylboronates via Carbon−Hydrogen Bond Cleavage
dramatically suppressed the reduction of the aromatic ketones and, as a result, ortho-arylation products were obtained in high yield based on the aromatic ketones. In these reactions, the aliphatic ketone functioned as a scavenger of ortho-hydrogens of the aromatic ketones and the B(OR)(2) moiety of the arylboron compound (HB species). A variety of aromatic ketones, such as acetophenones, acetonaphthones

A new and highly convenient Au-catalyzed cyclization of alkyne-propargylic acetates leading to 2-acyl-3-arylnaphthalene derivatives is described; these are possible candidates for light-emitting materials.
