Application

Molybdenum(VI) tetrachloride oxide can be used:
  • To prepare a binary metal catalyst (MoOCl4-n-BuLi) for the living polymerization of various acetylenes.
  • As an oxidant in the aromatization of various Hantzsch-1,4-dihydropyridines.
  • As a molybdenum (Mo) precursor to prepare nafion-Mo composite material, which is used as a catalyst for the preparation of nitrones by reacting primary amines with aldehydes.
