Electrospray ionization mass spectrometry of tributyltin(IV) complexes and their larvicidal activity on mosquito larvae: crystal and molecular structure of polymeric (Bu3Sn[O2CC6H4{NN(C6H3-4-OH(C(H)NC6H4OCH3-4))}-o])n

Abstract

A series of tributyltin(IV) complexes of 2-[(E)-2-(3-formyl-4-hydroxyphenyl)-1-diazenyl]benzoic acid and 4-[((E)-1-{2-hydroxy-5-[(E)-2-(2-carboxyphenyl)-1-diazenyl]phenyl}methylidene)amino]aryls have been investigated by electrospray mass spectrometry (ESI-MS) and tandem mass spectrometry (MS

Synthesis, characterization and crystal structures of polymeric and dimeric triphenyltin(IV) complexes of 4-[((E)-1-{2-hydroxy-5-[(E)-2-(2-carboxyphenyl)-1-diazenyl]phenyl}methylidene)amino]aryls

“…These tributyltin(IV) complexes have shown promise as larvicides [12,13]. In addition, the tributyltin(IV) complexes were investigated by electrospray ionization (ESI) mass spectrometry [13], which is considered to be the softest and most suitable ionization technique for the analysis of organotin compounds [14], including complex structures with molecular weights (M W s) over 1000 Da and high polarity.…”

Embryotoxicity studies of tri‐n‐butyltin(IV) complexes of 5‐[(E)‐2‐(aryl)‐1‐diazenyl]‐2‐hydroxybenzoic acid and 2‐[(E)‐2‐(3‐formyl‐4‐hydroxyphenyl)‐1‐diazenyl] benzoic acid on sea urchin development

“…As a continuation of previous work on the toxicity studies on the second instar of Aedes aegypti and Anopheles stephensi mosquito larvae, 26,27 the present report details a study of the toxicity studies of free 5- stages. The preparation of L 1 HH (Fig.…”

The Effectiveness of Organotin (IV) Benzylisopropyldithiocarbamate Compounds as Insecticide Against <i>Aedes Aegypti</i> Linn (Diptera: Culicidae) in Laboratory

“…Larvicidal effects of compounds A-C on Ae. aegypti mosquito larvae had also been better than triorganotin (IV) complex compound because compound A-C have higher LC 50 values (Baul et al, 2005). Organic group and ligand that attached to the tin atom were the main factor that influence the biological activity of organotin (IV) (Boraiko and Batt, 2005;Awang et al, 2010;Pellerito et al, 2006).…”

“…Several studies showed organotin (IV) compounds were effective against some pests like periplanata Americana, musca domestica, Spodoptera litura and Tetranychus urticae (Shukla et al, 2010) and a few species of larvae and adult mosquitoes like Aedes Aegypti and Aenopheles stephensi (Eng et al, 2003;Baul et al, 2005;. Group and the nature of organic group that bound to tin atom, such as the monoalkyl, dialkyl and trphenyl are the basic factors determining the biological activity (Boraiko and Batt, 2005;Awang et al,2010;Pellerito et al, 2006).…”
