α‐d‐Glucofuranose and α‐d‐allofuranose diacetonides 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‐dithiadiphosphetane‐2,4‐disulfide...
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‐disilylbisaryldithiophosphonate...
