series of cycloalkylidenebridged cyclopentadienyl metallocene complexes, [(CH2)nC(C5H4)2MCl2] (M = Ti, n = 4 (4), 5 (5), 6 (6); M = Zr, n = 4 (7), 5 (8), 6 (9); M = Hf, n = 4 (10), 5 (11), 6 (12)), have been synthesized and applied to ethylene polymerization after activation with methyl aluminoxane (MAO). The cycloalkylidene-bridged titanocene catalysts exhibit much higher activities than the corresponding zirconocene and hafnocene analogues, and have the highest activities at higher temperatures. In comparison, the silacyclopentylidenebridged metallocene complexes [(CH2)4Si(C5H4)2MCl2] (M = Ti (13), Zr (14)) and isopropylene-bridged metallocene complexes [Me2C(C5H4)2MCl2] (M = Ti (15), Zr (16)) have also been synthesized and applied to ethylene polymerization. In both cases, the titanocene complexes show much higher activities than the corresponding zirconocene analogues, especially at a lower temperature. The molecular structures of complexes 4-9 have been determined by X-ray diffraction. The structure-activity relationships, especially the effects of the bridges of ansa-metallocene complexes, are discussed.

Dimolybdenum complexes (X)(Y)[(η5-C5H3)Mo(CO)3]2 [Y ) Me2Si, X ) Me2C, (CH2)5C, CH2; Y ) Ph2Si, X) Me2C] and desilylation products (X)[(η5-C5H4)Mo(CO)3]2 were obtained from the reactions of carbon and silicon doubly bridged biscyclopentadiene ligands (X)(Y)(C5H4)2 with Mo(CO)6 in refluxing xylene. When these ligands reacted with W(CO)6, under similar conditions, in addition to ditungsten complexes (X)(Y)[(η5-C5H3)W(CO)3]2 [X ) Me2C; Y ) Me2Si, Ph2Si] and desilylation products (X)[(è5-C5H4)W(CO)3]2, a class of structurally novel complexes (X)(η5-C5H3)(η5,η1-5H3)[(Y)W(CO)3][W(CO)3] [for X ) Me2C, (CH2)5C; Y ) Me2-Si] with a W-Si bond were also isolated. The reactions of carbon and germanium doubly bridged biscyclopentadiene ligands (X)(Me2Ge)(C5H4)2 [X ) Me2C, (CH2)5C] with Mo(CO)6 or W(CO)6 gave similar novel complexes (X)(η5-C5H3)(η5,η1-C5H3)[(Me2Ge)M(CO)3][M(CO)3] [X ) Me2C, (CH2)5C; M ) Mo, W] with a M-Ge bond. The reactions also produced degermylation products. However, the corresponding dimolybdenum or ditungsten complexes were not isolated in these cases. The molecular structures of 2, 6, 8, 10, 11, 13, 14, 15, 19, 21, 22, 25t, and 26t have been determined by X-ray diffraction. The M-M distances in complexes 2 [3.4328 (12) Å], 8 [3.453 (2) Å], and 11 [3.403 (2) Å] are conspicuously elongated and are in fact the longest ever reported among the biscyclopentadienyl dimolybdenum or ditungsten complexes. The factors affecting the structures of dimolybdenum or ditungsten complexes are discussed.

The ansa-metallocene complexes Me2Ge(η5-C5Me4)2MCl2 [M=Ti (1), Zr (2)], Me2Ge(η5-C5H3Bu-t)2ZrCl2 (3) and Me2Ge(η5-C5H4)(η5-C5H3R)ZrCl2 [R=Me (4), t-Bu (5)] were prepared by the reaction of the corresponding ligands with n-BuLi and MCl4·2THF, respectively. The molecular structures of 1 and 2 have been determined by the X-ray diffraction method. Complexes 2-5 in combination with MAO were studied as catalysts for ethylene polymerization and all the germyl-bridged zirconocene catalysts show high activities at relative high temperatures. This indicates that the germyl-bridged zirconocene systems show thermally stable catalyst systems for polymerization of ethylene.

A series of doubly bridged dinuclear titanium and zirconium complexes Me2C)(Me2E)(C5H3)2(Cp'MCl2)2 [E=Si, Cp'=C5H5, M=Ti (1), Zr (2); E=Ge, Cp'=C5H5, M=Ti (3), Zr (4); Cp'=C5Me4H, M=Zr, E=Si (5), Ge (6)] and (Me2SiOSiMe2)2(C5H3)2(Cp[1]MCl2)2 [Cp[1]=C5H5, M=Ti (7), Zr (8); Cp[1]=C5Me4H, M=Zr (9)] were synthesized by the reaction of the lithium compounds of the corresponding doubly bridged cyclopentadienyl ligands with CpTiCl3, CpZrCl3(THF)2 or C5Me4HZrCl3, respectively. These complexes were characterized by 1H-NMR, MS and elemental analysis. The crystal structure of 4 was determined by the X-ray diffraction. Their catalytic properties for ethylene polymerization were also studied in the presence of MAO.

A series of aryl-substituted tetramethylcyclopentadienyl zirconocenes (C5Me4C6H4X-4)Cp'MCl2 [Cp'= C5H5, X = H (5), Me (6), Cl (7) or OMe (8); Cp'= Ind, X=H (9), Me (10) or Cl (11); Cp'=2-Ph-Ind, X = H (12)] and (C5Me4C6H4X-4)2ZrCl2 [X=H (13), Me (14), Cl (15)], with different substituents at the 4-position of phenyl, have been prepared by the reaction of the corresponding ligands (C5Me4HC6H4X-4) [X=H (1), Me (2), Cl (3) or OMe (4)] with n-BuLi, ZrCl4 and Cp[1]Li or with n-BuLi and ZrCl4. Ethylene polymerization with these complexes in combination with MAO has been studied. The electron donor (Me) at the 4-position of phenyl led to an increase in catalytic activity while the electron-withdrawing group (Cl) and the strong donor (OMe) led to its decrease. Complexes 5, 6, 9 and 10 exhibited very high activities, but 13-15 showed much lower activities due to the bulky steric effect. The molecular structure of 5 has been determined by X-ray diffraction. The relationship between structures of catalysts and catalytic activities were discussed.

The ansa-metallocene complexes Me2Si(η5-C5H4)(η5-C5Me4)MCl2 [M=Ti (1), Zr (2), Hf (3)] were prepared by the reaction of [Me2Si(η5-C5H4)(η5-C5Me4)]Li2 with MCl4·2THF. Complexes Me2Ge(η5-C5H4)(5-C5Me4)MCl2 [M=Ti (4), Zr (5)] were synthesized using similar method from the germyl-bridged ligand. The molecular structures of 1-3 and 5 have been determined by X-ray diffraction. Complexes 1-3 and 5 in combination with MAO were studied as catalysts for ethylene polymerization and it was found that zirconocene catalysts show much higher activities than the titanocene and hafnocene and the activities reach the maximum at high temperature. This indicates that the zirconocene system based upon [Me2E(C5H5)(C5Me4)]2 (E=Si, Ge) supporting coordination is a highly stable ethylene polymerization catalyst system. The relationship between structures and catalytic properties of catalysts is discussed.
