Identification of the transient benzonitrile n-sulfide by flash-vacuum pyrolysis and neutralization—reionization mass spectrometry

Using a combination of flash-vacuum pyrolysis and tandem mass spectrometry, it is shown that benzonitrile N-sulfide, 1, is a stable molecule in the diluted gas phase. This result is confirmed by neutralization—reionization experiments performed on a beam of the corresponding radical cations.
