Addition and Elimination Reactions with Sulfur Oxygen Compounds, II. Dihydroxyarylsulfones (and Quinonoid Secondary Products) by Reaction of Hydroxymethanesulfinate (Rongalit C ©) with QuinonesThe reaction of hydroxymethanesulfinate with 1,4- and 1,2-benzoquinone as well as with 1,4-naphthoquinone. which can be generated in situ from the corresponding dihydroxyaryl compounds by oxidation, yields symmetrical bis(dihydroxyaryl) sulfones (e. g. 2,7). Oxidation of bis(2,5-dihydroxyaryl) sulfones of type 2 does not lead to bis-quinones 3, but to oxathiin S,S-dioxide monoquinones (4, 6) by cyclisation.
Notes:
Die Umsetzung von Hydroxymethansulfinat mit 1,4- und 1,2-Benzochinon sowie 1,4-Naphthochinon, die aus den entsprechenden Dihydroxyarylverbindungen oxidativ in situ erzeugt werden können, führt zu symmetrischen Bis(dihydroxyaryl)sulfonen (z. B. 2,7). Die Oxidation der Bis(2,5-dihydroxyaryl)sulfone vom Typ 2 ergibt keine Bis-chinone 3, sondern unter Ringbildung Oxathiin-S,S-dioxid-monochinone (4, 6).
