Syntheses,Reactions, Characterization,and Antifungal Activities of Chloro-bis-(2,2-dithio-1,3,2-dioxaphospholane/dioxaphosphorinane)bismuth(III)

Abstract

Chloro-bis(2,2-dithio-1,3,2-dioxaphospholane/dioxaphosphorinane)bismuth(III) compounds have been synthesized by the reaction of bismuth trichloride with sodium 2,2-dithio-1,3,2-dioxaphospholane/dioxaphosphorinane in 1:2 molar ratio in benzene solution. Reactions of these chloro-bis(2,2-dithio-1,3,2-dioxaphospholane/dioxaphosphorinane)-bismuth(III) compounds with sodium tetraisopropoxyborate in equimolar ratio in benzene solution yield the corresponding heterobinuclear bismuth derivatives with boron. All compounds were characterized by elemental analyses and molecular weight measurements. Plausible structures are proposed on the basis of IR and ¹H, ¹¹B, ¹³C, and ³¹P spectroscopic studies. 2-Mercapto-2-thioxo-1,3,2-dioxaphospholanes-/dioxaphosphorinanes and the corresponding chloro-bis(2,2-dithio-1,3,2-dioxaphospholane/dioxaphosphorinane)bismuth (III) compounds show antifungal activities against Fusarium and Trichoderma.
