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.
Direct transformation of organosulfur compounds to organophosphorus compounds: rhodium-catalyzed synthesis of 1-alkynylphosphine sulfides and acylphosphine sulfides
A rhodium-catalyzed method for the synthesis of organophosphorus compounds directly from organosulfur compounds was developed. In the presence of RhH(PPh3)4 and depe, the reaction of 1-alkylthioalkynes with tetraethyldiphosphine disulfide gave 1-alkynylphosphine sulfides. The same complex catalyzed the reaction of thioesters giving acylphosphine sulfides.
