Synthesis, fungitoxicity and quantitative structure activity relationship of O-aryl O-2-chloroethyl O-ethyl phosphates

Nineteen new O-aryl O-2-chloroethyI O-ethyl phosphates 3 have been synthesised and tested for their fungicidal activity in vitro against Rhizoctonia bataticola and Alternaria alternate. O-2-Chloroethyl O-ethyl O- (pentachlorophenyl) phosphate 3s shows highest activity against both the tested fungi and possesses better activity compared to the standard ediphenphos. Quantitative structure activity relationship studies provide excellent correlation between fungicidal activities and physico-chemical parameters like hydrophobicity (Σπ), electronic effect (Σσ) and few position specific STERIMOL parameters like ΣL(o), ΣL(m), ΣB1(o) and Σ4(m) of phenyl ring substituents.
