Phenylthio (and phenylseleno)fluorination of alkenes and alkynes using N-phenylthio (and phenylseleno)phthalimide combined with pyridine*9HF or Et3N*3HF complexes
N-Phenylthiophthalimide and N-phenylselenophthalimide combined with pyridine*9HF or Et3N*3HF complexes allow the formal addition of elements of PHSF or PhSeF across the carbon-carbon double or triple bond by a one-pot reaction.Pyridine*9HF, a strongly aci
β-phenylselenofluorides have been synthesized by reaction of olefins (even acido-sensitive ones) with N-phenylselenophthalimide in the presence of triethylamine tris-hydrofluoride.Owing to the regioselectivity observed, this reaction constitutes a good me
