Abstract

A novel and efficient iodine-catalyzed C–N cleavage of tertiary amines via an sp3 C–H bond oxidative coupling reaction is described. A wide range of methylene-bridged bis-1,3-dicarbonyl compounds were synthesized in up to 92% yield by using an environmentally benign catalytic system in combination with 1,3-dicarbonyl compounds.
