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.

Mo(VI) and Mo(V) salts both react selectively with Hantzsch esters to produce substitute pyridines in good-to-excellent yield (75-99%). The remarkable reactivity and selectivity of MoOCl(4) under reflux of acetonitrile and MoCl(5) in dichloromethane at room temperature encouraged us to propose
