Abstract

© 2016 Taylor & Francis Group, LLC.Novel 2,4-diorganyl 1,3,2,4-dithiadiphosphetane-2,4-disulfideswere prepared by the reactions of tetraphosphorus decasulfide with butylphenyl ether or 3-brominephenyl-1-isoamyl ether in 1,2-dichlorobenzene. Their structures were established by X-ray single crystal diffraction. Chiral S-trimethylsilyl dithiophosphonates were prepared by the reactions of 2,4-diorganyl 1,3,2,4-dithiadiphosphetane-2,4-disulfides with trimethyl silyl ethers of monoterpenols. Unsaturated S-trimethylsilyl dithiophosphonates were synthesized by the reactions of 2,4-diorganyl 1,3,2,4-dithiadiphosphetane-2,4-disulfides with O-trimethylsilyl ethers of geraniol, nerol, and (R,S)-linalool. S-Esters of dithiophosphonic acids, which possessed antimicrobial activity, were prepared by the reactions of chiral S-trimethylsilyl dithiophosphonateswith orthoformiates, acetals and thioacetals.
