Pc. Vyas et al., SYNTHESIS AND INSECTICIDAL EVALUATION OF O-(PHENYL) O-(4-NITROPHENYL)O-(ALKYL BENZIMIDAZOLYL-2) PHOSPHOROTHIOATES/, Heterocyclic communications, 3(1), 1997, pp. 91-97
O-(phenyl)/O-(4-nitrophenyl)O-(alkyl benzimidazolyl-2) phosphorothioat
e derivatives were synthesized and-characterized on the basis of eleme
ntal analyses, M.P, IR, H-1 NMR and mass spectral studies. Their, inse
cticidal activity was evaluated against Periplanata americana (Indian
cockroach) by using contact and topical methods and were found to be q
uite active in this respect.
