ChemInform Abstract: Reactions of Arsinic and Arsonic Acids with H2S and H2Se: Crystal Structure of 3,5‐Diphenyl‐1,2,4‐triselena‐3,5‐diarsacyclopentane.

Abstract

The reaction of arsinic acids such as (I) or of arsonic acids such as (IV) with hydrogen sulfide (II) leads mainly to the formation of the trithiadiarsacyclopentanes (III) or (V).
