N-alkyl-2-pyridinylidenamido(phenyl)chlorothiophosphonates have been generated in situ by oxidative phosphorylation of N-alkyl-2-aminopyridinium halides through the intermediacy of functionalized halophosphines. As evident from the proton NMR spectroscopy, the generated chiral system had induced diastereotopicity in the geminal protons attached to a prochiral carbon atom. Due to the presence of an active chlorine atom, they have been used as precursors for the synthesis of novel bisamidothiophosphonates. The bioactive nature of these compounds has been established after bioassay against the fungi Alternaria alternata, Aspergillus flavus, Aspergillus niger, and Fusarium oxysporum and the insect Holotrichea Consanguinea.
