The reaction of hydrogen sulfide with several alkanethiosulfuric acids bearing amino functions has been studied. When primary and secondary aminoalkanethiosulfuric acids were treated with hydrogen sulfide, the product isolated in each case was the bis (aminoalky1) disulfide thiosulfuric acid salt. 2-Aminoethaneselenosulfuric acid gave the corresponding diselenide XIV. Of the five terl-amino compounds treated with hydrogen ...
