  A Pincer Ruthenium Complex for Regioselective C–H Silylation of Heteroarenes

  摘要：

  A pincer Ru(II) catalyst for the highly efficient undirected silylation of O- and S-heteroarenes with (TMSO)(2)MeSiH and Et3SiH is described, producing heteroarylsilanes with exclusive C2-regioselectivity, good functional group tolerance, and high turnover numbers (up to 1960). The synthetic utility of the silylated products is demonstrated by Pd-catalyzed Hiyama-Denmark cross-coupling under mild conditions. One-pot, two-step silylation and coupling procedures have been also developed.

  DOI：10.1039/c9cc05563k

  日期：——

  simple and effective Pd(II)-catalyzed regioselective C(2)–H arylation of 6,5-fused heterocycles with dioxazolones as a masked ester surrogate under mild conditions is reported. The significance of the arylation is highlighted by the new reactivity demonstrated in dioxazolones via proximal C–H activation of the cyclic carbonate of the hydroxamic acid functionality under protic conditions.

  Polymerization reaction is performed using a polymerizable monomer shown by the following general formula (1) and at least one monomer selected from monomers each having a structure of a salt among a lithium salt, a sodium salt, a potassium salt, and a nitrogen compound salt of a fluorosulfonic acid or the like; then, the structure of the salt of the repeating unit of a polymer obtained by the polymerization reaction is changed to the fluorosulfonic acid or the like by ion exchange. Thus, the present invention provides a polymer compound for a conductive polymer and a method for producing the polymer compound which is suitably used as a dopant for a fuel cell and a conductive material, and which is a copolymer containing a repeating unit of styrene having a 3,3,3-trifluoro-2-hydroxy-2-trifluoromethylisobutyl ether group, and a repeating unit having any of a fluorosulfonic acid, a fluorosulfonimide group, and a n-carbonyl-fluoro-sulfonamide group.
