摘要：

The binuclear complex [Cp2Zr(mu-Cl)(mu-CH2Me)AlMeEt] 1 attached to a support is formed by the reaction of [Cp2ZrMe2] and MgH2 after the addition of the cocatalyst (Et2AlCl)2. Species 1 catalyzes the polymerization of ethylene by inserting ethylene molecules into the Zr-mu-alkyl bond. The intermediate steps in the formation of 1 and the polymerization could be observed by means of C-13 CP/MAS NMR spectroscopy.
