  • alternative reaction pathway. Keywords: bromoalkenes; bromoketones; hypervalent iodine; oxidative hydrolysis; Ritter-type; Introduction Organic synthesis heavily relies on oxidative transformations to facilitate chemical reactions. One popular method for achieving these transformations is using redox-active
  • ], to access α-functionalized ketones. We recently developed the oxidative contraction of 3,4-dihydropyranones to access polysubstituted γ-butyrolactones [17]. In 2015 we demonstrated that [hydroxy(tosyloxy)iodo]benzene (HTIB) could be used to convert chloro- and bromoalkenes into their corresponding α

  • -bromoalkenes 72 was also investigated in the presence of Cs2CO3 without the need of a metal catalyst. The synthetic applicability of the procedure was demonstrated by a gram-scale synthesis of the 1,2-thiosulfonylethene product. A possible mechanism for the formation of 1,2-thiosulfonylethenes is shown in
