Investigations on the arbuzov and retro-arbuzov reactions among the organic derivatives of arsenic

Results of attempts to effect the Arbuzov and retro- Arbuzov reactions with esters of arsinous acid and with oxides and sulphides of tertiary arsines have been correlated. The general rules and special features of these conversions are considered as well as the reactions accompanying them as a function of the environment of the arsenic atom, the nature of the electrophilic reagent and the reaction conditions. Recent and previously known results are considered from a common position. © 1991 The British Library

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. © 2004 Wiley Periodicals, Inc

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. © 2004 Wiley Periodicals, Inc
