A micro‐flow nucleophilic trifluoromethylation of carbonyl compounds using gaseous fluoroform was developed. This method also allows the first micro‐flow transformation of N‐sulfinylimines into trifluoromethyl amines with excellent diastereoselectivity. To demonstrate the synthetic utility of this micro‐flow synthesis, the formal micro‐flow synthesis of Efavirenz is described.
