Conclusions
-
1.
Barenylsulfinic acids were obtained by the reaction of SO2 with the lithium and magnesium derivatives of barenes.
-
2.
Barenylsulfonic acids were obtained by the oxidation of barenylsulf inic acids in aqueous solution with potassium permanganate.
-
3.
Barenylsulfonyl halides were obtained by the reaction of halogens with barenylsulf inic acids or their lithium salts.
-
4.
The halogen atom in the barenylsulfonyl halides has a “positive” character.
-
5.
The basicity constants of a number of barenylsulfinic acids in water, and of a number of mercaptobarenes in 75% ethanol, were measured and it was found that the mercaptobarenes are strong acids.
