  摘要：

  2,6-Bis(chlormethyl)pyridine (1) reacts with 4 equivalents of indenyllithium with formation of 2,6-bis(methylenindenyl)pyridine-dilitihium (2) from which with MCl4 . 2thf (M = Zr, Hf) the corresponding metallocene dichlorides 3 and 4 can be obtained. At reaction of 1 with 2 equivalents of C5H5Na only one Cl atom is replaced by a C5H5Na unit. Following reactions with indenyl lithium and ZrCl4 . 2 thf give the unsymmetric complex [C5H3N-2,6-CH2-(2-C5H4)-(6-C9H6)ZrCl2] (7). - Picolylcyclopentadiene (8) and 1-(picolyl)-indene (9) are synthesized from 2-chlomethyl-pyridinium chloride and C5H5Na or indenyl lithium respectively, which are transferred in the half sandwich complexes (C5H4N-CH2C5H4)MCl3 (M = Ti 10, Zr 11) and (C5H4-CH2C9H6)ZrCl3 (12).The compounds were characterized by elemental analysis, H-1 n.m.r., ms, ir, and raman spectra. N --> M interactions are discussed.
