Recent advances in the direct synthesis of trifluoromethyl-containing heterocycles from trifluoroacetimidoyl chlorides (TFAICs) and derivatives, including trifluoroacetimidohydrazides (TFAIHs) and CF3–imidoyl sulfoxonium ylides (TFISYs), are system

We developed a palladium-catalyzed four-component carbonylative cyclization of alkenyl-tethered aryl iodides, trifluoroacetimidoyl chlorides and propargyl amines for the construction of carbonyl-bridged bisheterocycles.
