Über die gemeinsame Einwirkung von elementarem Schwefel und gasförmigem Ammoniak auf Ketone V. Die Gemeinsame Einwirkung Von Schwefel Und Ammoniak Auf Methyläthylketon

Abstract: Die gemeinsame Einwirkung von S und NH3 auf Methylathylketon liefert n i t guten Ausbeuten das bisher unbekannte 2.4.5-Trimethyl-2-athyl-thiazolin-A3 (I). Die Verbindung laBt sich im sauren Medium leicht in Methylathylketon, Amnioniak und 2-Mercaptobutanon-(3) aufspalten.Als Folgereaktion bildet sich, in Abhangigkeit von der Saurekonzentration, durch Wasserabspaltung aus dem 2-Mercaptobutanon-(3) das 2.3.5.6-Tetramethyl-2.S-endoxy-l.4-dithian. Die Vorstellungen uber den Reaktionsmechanismus sind dieselben wie … Show more

“…[ 15 ] Alternatively, α-sulfenylated carbonyl compounds are synthesized by the reaction of a carbonyl compound or a preformed enolate with sulfenylating agents such as disulfides, N -(phenylsulfanyl)succinimides, and sulfenyl chlorides (Scheme 2 , route B). [ 16 ] This alternative route also suffers from severe limitations of multiple reaction steps, toxicity, difficulty in handling intermediates, and low atom efficiency.…”
