Abstract

Neutral five-atomic cumulenes formally consisting of two pseudohalogens (e.g., NCO, NNN, NSO) by sharing the central nitrogen atom are exotic species that have been barely studied. Through flash vacuum pyrolysis of CF₃ S(O)NCO at ca. 1200 K, sulfinyl isocyanate, bearing resonance structures of O=C-N=S=O and O=C=N-S=O, has been generated in the gas phase and subsequently characterized in cryogenic matrices (Ar and N₂ ). Its reversible conformational (syn and anti) interconversion and photodecomposition were observed.

Keywords: IR spectroscopy; cumulenes; matrix isolation; pseudohalogens; sulfur-nitrogen compounds.
