Bisaryldithiophosphonic acids: Synthesis and their reactions with organyl chlorosilanes, germanes, stannanes, and plumbanes
A method of synthesizing arylbisdithiophosphonic acids was developed by the reaction of 2,4-diaryl 1,3,2,4-dithiadiphosphetane-2,4-disulfides with tri(ethylene glycol) and 1,4-butandiol in anhydrous benzene suspension under mild conditions. The arylbisdithiophosphonic acids thus obtained were transformed into the corresponding diammonium salts. New bis(triorganylgermyl), stannyl and plumbyl, and cyclic diphenylsilyl and diphenylplumbyl derivatives of arylbisdithiophosphonic acids were prepared from the reactions of diammonium salts of the corresponding acids with triorganylchlorogermane, chlorostannane, chloroplumbane, diphenyldichlorosilane, and diphenyl dichloroplumbane
The reaction of triphenylarsine oxide with ethyl Iodo-acetate leading to triphenyl (carboethoxy)methylarsonium triiodide
New data are presented for some processes accompaning "retro-Arbuzov" reaction of tertiary arsine oxides with halogen-containing reagents. Triphenyl (carboethoxy)methylarsonium triiodide 10a was obtained in the reaction of triphenylarsine oxide la with excess of ethyl iodoacetate 2a. The structure of 10a was established by X-ray single crystal diffraction. 漏 2004 Wiley Periodicals, Inc
Thiophosphorylated resorcinol, calix[4]resorcinols, and other hydroxyphenols
Perdithiophosphonic acids are new types of tetracoordinated phosphorus thioacids bearing many dithiophosphoryl groups. Novel perdithiophosphonic acids were obtained by the reactions of 2,4-diaryl-1,3,2,4-dithiadiphosphetane-2,4- disulfides with hydroxyphenols such as resorcinol, 4,4'-iso- propylidenebisphenol, pyrogallol, and calix[4]resorcinols.

Disilyl dithiophosphonates in the synthesis of open chain and cyclic organothiophosphorus compounds
O-(Trimethylsiloxy)alkyl S-trimethylsilyl aryldithiophosphonates 7a-d were obtained by the reaction of 2,4-diaryl-1,3,2,4-dithiadiphosphetane-2,4- disulfides 5a,b with disilyl derivatives of glycols 6a,c and salicyl alcohol 6b. The reactions of mixed O,S-bis(trimethylsilyl) 2,4-di(3,5-di-tert-butyl-4- hydroxyphenyl)dithiophosphonate 1 and S-silyl aryldithiophosphonates 7a,b with S,S-diethyldithiodiphenylgermane 2, dichlorodiphenylgermane 8a, and dichlorodiphenylstannane 8b were studied. The structure of hexaphenyl-2,4,6,1,3, 5-trithiatrigerminane 11 was established by X-ray single crystal diffraction. 漏 2004 Wiley Periodicals, Inc
