Generation of nitrile N-selenides, RC≡NSe, as neutrals and radical cations in the gas phase

Cyanogen N-selenide radical cation, NCCNSe^.+, is prepared by dissociative ionization of 3,4-dicyano-1,2,5-selenadiazole [1]. It reacts readily with nitriles in the gas phase to produce nitrile N-selenide ions, RCNSe^.+. The stability of the corresponding neutral dipoles is confirmed by neutralization-reionization mass spectrometric experiments.
