2-aminophenyl benzyl sulphide proved to be identical with the compound previously obtained by quaternisation. The higher alkyl quaternary salts have been prepared by use of the alkyl esters of 2,4-dinitrobenzenesulphonic acid. Methyl and ethyl quaternary salts of the unstable base 1,2,3-benzoselenadiazole are reported.

The reduction of a group of thiazoliumsalts with sodiumborohydride has been investigated with particular reference to the influence on the course of the reaction of different 2-substituents. The behaviour of the thiazoliumsalts with aqueous base is also considered.
