Application

Bis(hexylene glycolato)diboron can be used as a reagent:
  • To prepare aryl boronate esters via metal-catalyzed direct C-H borylation of aryl compounds.
  • In the chemoselective synthesis of C−C coupling products via nickel catalyzed coupling of primary and secondary alkyl halides.
  • In the nickel-catalyzed regioselective arylboration of terminal nonactivated alkenes to yield alkyl boranes.
