Uses
4-(Trifluoromethyl)benzenesulfonyl chloride may be used to synthesize β-arylated thiophenes and 2,5-diarylated pyrrolevia palladium catalyzed desulfitative arylation of thiophenes and pyrroles, respectively.
4-(Trifluoromethyl)benzenesulfonyl chloride and
N-vinylpyrrolidinone in acetonitrile can undergo photo-irradiation with visible light in the presence of Ir(ppy)
