The reaction of 2,4-diaryl 1,3,2,4-dithiadiphosphetane-2,4-disulfide with diketonide of d-mannitol has been found to give optically active bisaryldithiophosphonic acids transformed into the corresponding diammonium salts by the treatment of n-hexadecylamine. O,O-Bis(trimethylsilyl) ether of d-mannitol ketonide reacts with 2,4-diaryl 1,3,2,4-dithiadiphosphetane-2,4-disulfide to form chiral S,S-disi

α-d-Glucofuranose and α-d-allofuranosediacetonides react with 2,4-diorganyl 1,3,2,4-dithiadiphosphetane-2,4-disulfides to form optically active dithiophosphonates in 78–81% yields, which are transformed into the corresponding ammonium salts in 90–97% yields by the treatment of n-hexadecylamine. The S-silyldithiophosphonate was prepared in 93% yield by the reaction of 2,4-bis(butoxyphenyl) 1,3,2,4

Bis(trimethylsilyl) esters of bisaryldithiophosphonic acids were obtained in 70–81% yields by the reactions of 2,4-diaryl 1,3,2,4-dithiadiphospheta ne-2,4-disulfides with 1,3-bis(trimethylsilyloxy)benzene and 2-methyl 1,3-bis(trimethylsilyloxy)benzene. GRAPHICAL ABSTRACT

Opticallyactive dithiophosphoric and dithiophosphonic acids bearing glucofuranose and galactopyranose diacetonide substituents reacted with racemic atropine to give atropinium dithiophosphates or dithiophosphonates as the mixture of diastereomers. Dithiophosphoric and dithiophosphonic acids and their atropinium salts possess antimicrobial activity. Graphical abstract SYNOPSIS: Opticallyactive dithiophosphoric

Carvacrol trimethylsilyl ether when reacting with P4S10 forms S-trimethylsilyl ester of O,O-bis(5-isopropyl-2-methylphenyl)dithiophosphoric acid. The reactions of 2,4-diorganyl-1,3,2,4-dithiadiphosphetane-2,4-disulfides with carvacrol (thymol) trimethylsilyl ether yield the S-trimethylsilyl esters of the corresponding dithiophosphoric acids.
