  Extremely facile ligand-exchange and disproportionation reactions of diaryl sulfoxides, selenoxides, and triarylphosphine oxides with organolithium and Grignard reagents

  摘要：

  Diaryl sulfoxides undergo unusually rapid ligand-exchange reaction upon treatment with organolithium reagents at -95-degrees-C. Optically pure phenyl p-tolyl sulfoxide (4b) reacted with organolithium reagents at the range from -20 to -95-degrees-C to give facile ligand-exchange and disproportionation products, i.e., diphenyl sulfoxide (7), recovered 4b, and di-p-tolyl sulfoxide (8) in a statistical ratio of 1:2:1 in quantitative yields, and the recovered 4b was completely racemized. This facile ligand exchange was observed in the similar reactions using only diaryl selenoxides and triarylphosphine oxides. The reactions of O-18-labeled phenyl p-tolyl sulfoxide (4c) with organolithium reagents gave products in a statistical ratio without O-18 scrambling, indicating that only the C-S bond cleavage took place under low temperature. It is suggested that the ligand exchange reactions occur by the nucleophilic attack by organolithium reagent at the sulfinyl sulfur atom, giving sigma-sulfurane as an intermediate that collapses rapidly. These results suggest that the treatment of arylic sulfoxides, selenoxides, and phosphine oxides with strong bases should be effected with caution.

  A variety of Ni(II) complexes with a wide range of electronic and steric properties, bearing picolyl-imidazolidene ligands (a-g) and Cp (2a-f) or Cp* (3a,c,g) groups, have been synthesised and characterised using NMR and single crystal X-ray crystallography. The complexes have been used as precatalysts for a wide range of catalytic transformations most likely involving a Ni0/NiII catalytic cycle. In

  Removable and versatile: The 2‐pyridylsulfinyl group has proved to be an efficient directing group in the PdII‐catalyzed aryl ortho CH olefination. This catalyst system enables the sequential double olefination to give asymmetrically di‐ortho‐functionalized arenes. The sulfinyl directing group can be easily cleaved, providing access to 1,3‐disubstituted arenes, or transformed into a thiol group.
