2,2′ disubstituted phosphonothioic or phosphonic dihydrazides 3a-p or 3a′-g′ and 2,2′,2″ trisubstituted phosphonothioic or phosphonic trihydrazides 4a-e, 4i-l or 4a′-h′ were prepared in high yields by reacting phosphonothioic or phosphonic di- or trihydrazides 1a,a′,b or 2a,a′ with various aldehydes. The structure of one of these compounds 4a′ was solved by X-ray analysis.
