Synthesis and structure elucidation of new series of organotin(IV) esters with bio-screening activity and catalytic study

A new series of fourteen numbers of organotin(IV) esters with NNDEG and NNDBG is being described. On the basis of IR, 1H-, 13C-NMR, Mass and Mössbauer spectroscopic studies and elemental analysis data, an interesting sinusoidal view of dimeric organotin(IV) is proposed and octahedral geometry is suggested for monomeric organotin(IV) esters while triorganotin(IV) complexes are assigned trigonal bipyramidal and tetrahedral geometry which is confirmed by 1H NMR. All the OTCs except 1, 4, 8 and 10 exhibited excellent rate of mortality against selected insects. OTCs (2, 6, 9, and 11) at 500 ppm showed a two-fold positive role than standard drug Enoxacin as an antibiotic against the selected bacterial strains. ED50 of all OTCs is also reported here. The catalysis study of monomeric OTCs give 80% yield while dimeric OTCs give 100% yield of benzylacetate in six hours of reaction time.
