Synthesis, Characterization, and Biotoxicity ofNN⌢Donor Sulphonamide Imine Silicon(IV) Complexes

Abstract

The organosilicon derivatives of2-[1-(2-furayl)ethyledene]sulphathiazole with organosilicon chlorides have been synthesised and characterized on the basis of analytical, conductance, and spectroscopic techniques. Probable trigonal bipyramidal and octahedral structures for the resulting derivatives have been proposed on the basis of electronic, IR,1H,13CNMR, and29SiNMR spectral studies. In the search for better fungicides, bactericides, nematicides, and insecticides studies were conducted to assess the growth-inhibiting potential of the synthesized complexes against various pathogenic fungal, bacterial strains, root-knot nematodeMeloidogyne incognita, and insectTrogoderma granariumThese studies demonstrate that the concentrations reached levels which are sufficient to inhibit and kill the pathogens, nematode, and insect.
