Synthesis, characterization, and insecticidal activity of new tin (IV) complexes

Listed in DataCite

A three-component reaction of dimethyltin dibromide with imidazo[1,2- a ]pyridine, pyridine derivatives, or isoquinoline and allyl bromide in refluxing ethanol affords the ionic complex, bis(1-allylcycloiminium) dimethyltetrabromostannate (II).

Description

The reaction involves N-allylation of cycloimine accompanied by the coordination of two bromide ions with the tin atom of dimethyltin dibromide. The complexes have been characterized by infrared and 1 H NMR, 13 C NMR, and 119 Sn NMR studies.

The X-ray crystal structure analysis of a complex reveals the tin atom to be hexacoordinated and the dimethyltetrabromostannate (II) anion having octahedral geometry. Some of the complexes tested for their insecticidal activity are found to exhibit strong activity against Tribolium castaneum insect with LC 50 ranging from 0.4 to 0.8 ppm.
