Shedding new light on the right combination of catalysts: A new dual catalytic system for efficient CH functionalization was developed. The appropriate choice of two metal catalysts allows the oxidativealkynylation of tertiary amines under mild and sustainable reaction conditions.

convenient and efficient method for oxidative coupling of tetrahydroisoquinoline derivatives with trimethyl(trifluoromethyl)silane and terminalalkynes to 1-trifluoromethylated or 1-alkynylated tetrahydroisoquinolines via CH activation was developed using visible light irradiation. The protocol uses Rose Bengal as the catalyst, air as terminal oxidant, and the trifluoromethylation or alkynylation was selectively
