Abstract

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. Abstract : Heterocumulene OCNSO, an interpseudohalogen by sharing the central nitrogen atom, was generated in the gas phase through flash vacuum pyrolysis of CF3 S(O)NCO at 1200 K. Two conformers of OCNSO and their reversible interconversion in cryogenic (2.8–15 K) matrices were observed.
