摘要：

Mo(PMe(3))(6) reacts with ArOH (Ar = C(6)H(2)Me(3), C6H3Pr2i) to give aryloxy-hydride derivatives Mo(PMe(3))(4)-(OAr)H in contrast to the cyclometalated derivatives that are obtained for the corresponding tungsten system. Deuterium labeling and magnetization transfer studies, however, demonstrate that the coordinatively unsaturated molybdenum complexes Mo(PMe(3))(4)(OAr)H are in fact kinetically capable of intramolecular oxidative addition of a C-H bond to yield cyclometalated derivatives but that the products so obtained are thermodynamically unstable with respect to the aryloxy-hydride derivatives.
