Organic Compounds Containing Bonds between Se or Te with P, As, Sb and Bi

摘要: This chapter describes syntheses, structures, and reactions of the compounds with phosphorus-selenium double bonds at least one carbon-phosphorus single bond their heavier congeners. Among them, phosphane selenides have been most deeply studied used as Lewis base catalysts, metal ligands, molecular sensors, stating materials leading to selenium-containing nanoparticles. The coupling constants between phosphorus selenium atoms are informative on basicity phosphanes. Phosphinoselenoic acid chlorides secondary phosphanes frequently precursors give a range phosphinoselenoic derivatives, whereas selenation dichlorophosphanes leads phosphonoselenoic dichlorides, which converted variety derivatives. phosphinites also gives O-esters. Stereochemical course substitution reaction P-chiral center in has elucidated. Some dimers diselenoxophosphanes such Woollin's reagent shown. finally examples tellurides, arsenic, antimony, bismuth isologues selenides, although these fewer.
