Matrix isolated 1,2-oxathietan-4-one 2-oxide: a 2π+ 2π adduct of sulphur dioxide and keten
Abstract
U.v. irradiation of mixtures of SO2 and keten in argon or nitrogen matrices at 10–20 K gave an adduct, identified on the basis of its i.r. spectrum and photodecomposition to carbon dioxide, as 1,2-oxathietan-4-one 2-oxide (5).
