Abstract

Some organotin(IV) and tin(II) complexes of composition R3Sn[ R COC:CON¯(C¯6¯H¯5¯)N:C¯CH3] (where R=C4H9, R=CH3 , C3H5 ,p-ClC6H4 ; R=C6H5 , R=C6H5 and p-ClC6H4 ) and Sn[p-ClC6H4COC:CON¯(C¯6¯H¯5¯)N:C¯CH3]2 were screened for their toxicity against Aedes aegypti larvae. Organotin(IV) complexes were more active than tin(II) complexes.
