Studies on the Preparation and Properties of Molybdenum Oxy Phenoxides

Abstract

Reactions of molybdenum oxy tetrachloride with mono‐, di‐, and trihydroxy phenols have been carried out and molybdenum oxy phenoxides isolated. Alternative method for the preparation of these oxy phenoxides by the interaction between molybdenum oxy tetraethoxide and corresponding phenols has been reported. I. R. spectra of the oxy phenoxides have been discussed.

Facile Formation of Molybdenum(VI) Monooxo Aryloxides MoO(OAr)4-nClnfrom Molybdenum Dioxo Dichloride

“…9 The molybdenum(VI) complex is photolabile and prone to disproportionation to chlorine and Mo(V) products, and it must be freshly prepared before use. 10 Although there is an old report of MoOCl 4 + ArOH yielding the corresponding oxo aryloxides, 11 this has never been confirmed and was not reproducible by us. Hayano et al reported the successful formation of MoO(OAr) 4 for several mono-and multidentate aryloxy ligands by the low-temperature reaction of MoOCl 4 with the corresponding aryloxy anions, but the yields are low and the characterization minimal.…”
