Sulphonohydrazides and related compounds. Part XIII. Some sulphanilohydrazides
Abstract
N-Carbamoylsulphanilyl chloride has been condensed with hydrazine and the hydrazide converted into hydrazones. Similarly NN′-diphenylurea has been converted into the 4,4′-bis-sulphonyl azide. Attempted chlorosulphonation of NN′-di-o-,-m-, and -p-tolylureas gave the corresponding bis-sulphonic acids. Reaction of p-succinimidobenzenesulphonyl chloride with hydrazine gave N-(4-hydrazino-4-oxobutyryl)sulphanilohydrazide.
