A Rh(iii)-catalyzed and weak coordination carbonyl guided direct C4 alkylation of indoles with allylic alcohols was developed with excellent regioselectivity. This reaction was conducted under mild conditions, leading to a variety of β-indolyl ketones with good functional group tolerance in moderate to good yields.

Transition-metal-catalyzed remote spCH functionalization of arylsulfonicacids was hardly ever realized owing to competitive -CH functionalization of aryl sulfonates and electron-deficient nature of phenyl ring. Herein, with the assistance of a practical biaryl indolyl directing template, palladium-catalyzed remote spCH alkylation of arylsulfonicacids have been achieved in moderate to good yields with exclusive
