Rhodium-catalyzed thiophosphinylation and phosphinylation reactions of disulfides and diselenides
摘要:
Alkyl and aryl dithiophosphinates were synthesized by the reaction of disulfides with biphosphine disulfides in the presence of RhH(PPh3)(4) and 1,2-diphenylphosphinoethane (dppe). The catalyst also promoted synthesis of thiophosphinates and selenothiophosphinates from disulfides and diselenides. (c) 2005 Elsevier Ltd. All rights reserved.
Dialkyl(heteroaryl)phosphine sulfides were synthesized by the rhodium‐catalyzed exchange reaction of heteroaryl aryl sulfides and tetraalkyldiphosphine disulfides. The reaction has a broad applicability, giving diverse dialkyl(heteroaryl)phosphine sulfides containing five‐ and six‐membered heteroaryl groups. Various dialkyl(heteroaryl)phosphines were obtained by desulfurization.
