Syntheses of Molybdenum Oxo Benzylidene Complexes.

ABSTRACT: The reaction between Mo(O)(CHAr_o)(OR_F6)₂(PMe₃) (Ar_o = ortho-methoxyphenyl, OR_F6 = OCMe(CF₃)₂) and 2 equiv of LiOHMT (OHMT = O-2,6-(2,4,6-Me₃C₆H₂)₂C₆H₃) leads to Mo(O)(CHAr_o)(OHMT)₂, an X-ray structure of which shows it to be a trigonal bipyramidal anti benzylidene complex in which the o-methoxy oxygen is coordinated to the metal trans to the apical oxo ligand. Addition of 1 equiv of water (in THF) to the benzylidyne complex, Mo(CAr_p)(OR)₃(THF)₂ (Ar_p = para-methoxyphenyl, OR = OR_F6 or OC(CF₃)₃ (OR_F9)) leads to formation of {Mo(CAr<
