  Structure and reactivity of thiophanium salts, the elusive intermediates in ArS+-mediated one-pot sequence of three AdE reactions

  摘要：

  The structure of the previously postulated cationoid intermediate, presumably formed in ArS+-mediated coupling of two vinyl ether units, was firmly established as (1R*,2R*,4S*)-2,4-dimethoxy-3,3-dimethyl-1-p-tolylthiophanium salt and its reactivity was elucidated (C) 1998 Elsevier Science Ltd.

• Reaction sequence arylsulfenyl chloride + alkoxyalkene-I + alkoxyalkene-II + allylmagnesium or boron derivatives as a new method for the controlled synthesis of polyfunctional derivatives

  日期：1991.5

  A new method is proposed for the controlled synthesis of polyfunctional compounds with formation of two new carbon-carbon bonds; the method is based on the following reaction sequence, which can be carried out in a single flask: addition of ArSCl to vinyl ether I, reaction of the resultant adduct with vinyl ether II in the presence of Lewis acid to form a cationic complex, and treatment of the latter with allyl derivatives of boron or magnesium.
