Über die Umsetzung von Polysulfiden mit Stickstoffmonoxid in nichtwäßrigen Lösungsmitteln — Nitrosodisulfide / The Reaction of Polysulfides with Nitrogen Monoxide in Non-Aqueous Solvents — Nitrosodisulfides

Abstract

Abstract Polysulfides dissolved in non-aqueous solvents react under anaerobic conditions with nitric oxide to yield solutions of nitrosodisulfides. Through the action of NO upon (PNP) 2 S 12 1 [P = P(C 6 H 5 ) 3 ] in acetone a stable compound PNP · SSNO 2 could be obtained. 2 proved to be identical with a red PNP-salt which had been isolated as a product of the reaction of PNP·NO 2 with sulfur in acetone, hitherto taken for PNP · SSNO 2 . Clearly the product 3 of the action of triphenylphosphane upon 2 has to be regarded as PNP·SNO.
