Unterphosphorige Säure lagert sich an die Doppelbindungen von Phenylhydrazonen, Acylhydrazonen, Azinen und Oximen zu Derivaten von Hydrazin‐ und Hydroxylaminphosphonigsäuren I, VII, X und XV an. Die Hydrazin‐Derivate können auch aus Carbonylverbindungen, Hydrazin oder substituierten Hydrazinen und unterphosphoriger Säure dargestellt werden.

A series of benzylidene hydrazides (1-20) was synthesized and tested, in vitro, for antibacterial, antifungal and antiviral activities. The microbial screening results indicated that compounds having chloro and nitro substituents were the most active ones. The antiviral evaluation depicted that compounds 9 and 19 were active against Vesicular stomatitis virus (VSV) in HeLa cell cultures. QSAR investigations indicated that the multi-target QSAR model was effective in describing the antimicrobial (antibacterial and antifungal) activity over the one-target QSAR models. Further the mt-QSAR model indicated that the topological parameters, second order molecular connectivity index ((2)chi) and third order Kier's alpha shape index (kappa alpha(3)) are effective in describing the antimicrobial activity of synthesized hydrazides.
