Application

Nickel(II) bromide 2-methoxyethyl ether complex can be used as a catalyst to prepare:
  • Hindered diarylmethanols and benzylic alcohols by the addition of aryl halides to various aldehydes in the presence of Zn as a reducing agent.
  • Benzene-fused cyclic compounds via reductive dicarbofunctionalization of unactivated alkenes using less reactive benzyl chlorides.
  • Benzylboron derivatives via C-C cross-coupling reaction between substituted 5-bromo-3-methoxy-2-(trimethylsilyl)phenyl triflate and bromomethylboronic acid pinacol ester.
  • N-(Hetero)aryl sulfamides by N-arylation of sulfamides with aryl bromides in the presence of a photosensitizer.
