Phosphinoyl and thiophosphinoylcarbodithioates: Synthesis, molecular structure, and application as new efficient mediators for RAFT polymerization

New phosphinoyl and thiophosphinoylcarbodithioates were synthesized in a one-pot reaction from the corresponding phosphinochalcogenides. Compounds of this new generation of thiocarbonylthio derivatives have been fully characterized by IR as well as 1

Metal-free SHNcross-coupling of pyridines with phosphine chalcogenides: polarization/deprotonation/oxidation effects of electron-deficient acetylenes

Terminal acylacetylenes, typical electron-deficient acetylenes, drive SHNcross-coupling of pyridines with secondary phosphine chalcogenides under metal-free mild conditions (20-75 °C) to afford 4-chalcogenophosphorylpyridines in up to 70% yield. The reaction proceedsvia2,4-migration of chalcogenophosphoryl groups in the intermediate 1-acylvinyl-2-phosphoryl dihydropyridines with simultaneous redox elimination of the vinyl ketone oligomers. These results are generalized in a concept of trimodal (polarization/deprotonation/oxidation) catalyst-like assistance of electron-deficient acetylenes in SHNreaction of the pyridinoid heterocycles with PH-nucleophiles, which comprises: (i) repolarization (umpolung) of the pyridine ring, (ii) deprotonation of secondary phosphine chalcogenides to generate phosphorus-centered anions and (iii) oxidation of the dihydro intermediates.

Metal-free site selective cross-coupling of pyridines with secondary phosphine chalcogenides using acylacetylenes as oxidants

Pyridines undergo site selective cross-coupling with secondary phosphine chalcogenides (oxides, sulfides, and selenides) in the presence of acylphenylacetylenes under metal-free mild conditions (70-75 °C, MeCN) to afford 4-chalcogenophosphoryl pyridines in up to 71% yield. In this new type of SNHAr reaction acylacetylenes act as oxidants, being stereoselectively reduced to the corresponding olefins of the E-configuration.

Non-catalyzed addition of secondary phosphine chalcogenides to divinyl chalcogenides under solvent-free conditions

Secondary phosphine chalcogenides, R2PX (R═(CH2)2Ph, Ph; X = S, Se), react with divinyl chalcogenides, (CH2═CH)2Y (Y = S, Se, Te), at the 2:1 molar ratio (80–82°C, 56–80?h) in the absence of both cata
