Bisaryldithiophosphonic Acids: Synthesis and Their Reactions with Organyl Chlorosilanes, Germanes, Stannanes, and Plumbanes

1,2:5,6-Di-O-Cyclohexylidene-d-Mannitol and Its Bis(Trimethylsilyl) Ether in the Dithiophosphorylation Reactions

“…Indeed, we have previously shown that bisalkyldithiophosphonic acids react with acetonitrile to form cyclic alkyltrithiopyrophosphonates and thioacetamide . On the other hand, anhydrous benzene seems to be the most appropriate inert solvent for successful synthesis of stable bisaryldithiophosphonic acids . New bisdithiophosphonic acids were prepared on the basis of the reactions of dithiadiphosphetanes 1 with tri(ethylene glycol), 1,4‐butandiol, (+)‐dimethyl L ‐tartrate, ethambutol dihydrochloride, and trans ‐3,4‐pinanediol in the anhydrous benzene suspension under mild conditions .…”

“…On the other hand, anhydrous benzene seems to be the most appropriate inert solvent for successful synthesis of stable bisaryldithiophosphonic acids [27][28][29][30]. New bisdithiophosphonic acids were prepared on the basis of the reactions of dithiadiphosphetanes 1 with tri(ethylene glycol), 1,4-butandiol, (+)-dimethyl L-tartrate, ethambutol dihydrochloride, and trans-3,4-pinanediol in the anhydrous benzene suspension under mild conditions [27][28][29][30]. Some of bisdithiophosphonic acids [28][29][30] possess optical activity.…”

“…It should be emphasized that bisdithiophosphonic acids previously obtained were transformed into the corresponding diammonium salts, which have been used for the synthesis of bis(triorganylgermyl), stannyl, and plumbyl derivatives . The similar diammonium salts can be prepared by the treatment of acids 3a,b with ammonia or alkylamines.…”

Reaction of 2,4-Diaryl-1,3-dithia-2,4-diphosphetane-2,4-disulfides with resorcinol

“…[3][4][5][6][7][8][9]. The reactions of 2,4-dialkyl-or diaryl-1,3-dithia-2,4-diphosphetane-2,4-disulfides with glycols are used to obtain bisdithiophosphonic acids [1][2][3][4][5][6][7][8].…”

Thiophosphorylation of calix[4]resorcinarenes with 2,4-diaryl-1,3-dithia-2λ5,4λ5-diphosphetane 2,4-disulfides

“…We propose to obtain such compounds via reactions of calixarenes with 2,4-diaryl-1,3-dithia-2λ 5 ,4λ 5 -diphosphetane 2,4-disulfides as thophosphorylating agents. It is known that 2,4-dialkyl-or 2,4-diaryl-1,3-dithia-2λ 5 ,4λ 5 -diphosphetane 2,4-disulfides react with alcohols, diols, and other polyhydric alcohols at the O-H bonds with formation of aryldithiophosphonic, bis-aryldithiophosphonic, and poly-aryldithiophosphonic acids [16][17][18][19][20][21][22][23][24]. Calix [4]resorcinarene II reacted with 2,4-diaryl-1,3-dithia-2λ 5 ,4λ 5 -diphosphetane 2,4-disulfides Ia and Ib at a molar ratio of 1 : 4 in benzene to give octa-O-(2,4,6,8-tetraheptyl-1,3,5,7(1,3)-tetrabenzenacyclooctaphane-1 4 ,1 6 ,3 4 ,3 6 ,5 4 ,5 6 ,7 4 ,7 6 -octayl) octakis(hydrogen arylphosphonodithioates) IIIa and IIIb (Scheme 1).…”
