Phosphine Chalcogenides

Pyridines are easily cross-coupled with secondary phosphine chalcogenides in the presence of acylphenylacetylenes under mild conditions to afford 4-chalcogenophosphorylpyridines.

Publications covering a new easy metal-free functionalization of pyridinoids (pyridines, quinolines, isoquinolines, acridine) under the action of the system of electron-deficient acetylenes (acetylenecarboxylic acid esters, acylacetylenes)/P-nucleophiles (phosphine chalcogenides, H-phosphonates) are reviewed. Special attention is focused on a SNH reaction of the regioselective cross-coupling of pyridines with secondary phosphine chalcogenides triggered by acylacetylenes to give 4-chalcogenophosphorylpyridines. In these processes, acetylenes act as three-modal adjuvants (i) activating the pyridine ring towards P-nucleophiles, (ii) deprotonating the P-H bond and (iii) facilitating the nucleophilic addition of the P-centered anion to a heterocyclic moiety followed by the release of the selectively reduced acetylenes (E-alkenes).

Phosphine chalcogenides react with primary amino alcohols in a CCl4/Et3N system to chemoselectively deliver chalcogenophosphinic acids amides with free OH groups. Similar reaction for aminophenols gives exclusively chalcogenophosphinic O-esters.
