Synthesis and Fugicidal Activities of 2-Silatranyl Propylamino-4-substitued Phenyl(Hydrogen)-5,5-dimethyl-1,3,2-dioxaphosphinanes-2-oxides (Sulfides)

Abstract

Phosphoryl-aminopropyl-silatranes 4 were synthesized by nucleophilic reactions of 2-Cl-1,3,2- dioxaphosphinanes 2 with γ -aminopropyl-silatrane 3 , which was obtained by the cyclization reaction of triethanolamine and γ -aminopropyltriethoxysilane. The structures of the products were characterized by 1 H NMR, 31 P NMR, IR, MS, and elemental analyses. The target compounds 4 exhibited fungicidal activity.
