    摘要:
    The isotopomeric complexes trans-W(Cmesityl)[(C(H,D)(3))(2)PCH2CH2P(C(H,D)(3))(2)](2)(H,D) 1-4 were prepared. 2 (W(C-mesityl)(dmpe)(2)D) was used to study the Deuterium Quadrupole Coupling Constant (DQCC) and the ionicity of the W-D bond (DQCC = 34.1 kHz; ionicity 85%). 1 (W(C-mesityl)(dmpe)(2)H) shows several dynamic exchange processes in solution, such as H-W/H-W, H-W/ortho-Me-mesityl, and H-W/H-2 exchanges observed by NMR in combination with deuterium labeling studies and double label crossover experiments. Except for the H-W/H-2, these reactions comprise elementary steps, which also appear along the isomerization pathway of 1 into (2,3,5-trimethylphenylcarbyne)(dmpe)(2)WH (5) at 60 degrees C. 5 was characterized by an X-ray diffraction study. In the solid state only an H-W/Me-p exchange process prevails appearing at higher temperatures, which was identified by NMR and by Quasielastic Neutron Scattering. The latter also provided an activation barrier of 5 kcal/mol and a "jump width" for the moving H nucleus in agreement with the H-W center dot center dot center dot Me-p distance of the X-ray diffraction study of 1.
