Cyclooctatetraenyl-komplexe der frühen Übergangsmetalle und lanthanoide
摘要:
[(COT)Ti(mu-CI)(THF)]2 (1) reacts with K[HBpz3] or K[HB(3,5-Me2pz)3] to give the new monocyclooctatetraenyl half-sandwich complexes (COT)Ti[HBPZ3] (2) and (COT)Ti[HB(3,5-Me2PZ)3] (3) respectively, as dark green, air-sensitive solids (COT = eta8-cyclooctatetraenyl(2-)). The molecular structure of 2 has been determined by an X-ray diffraction study. The monomeric organotitanium(III) complexes (COT)Ti[PhC(NSiMe3)2](THF) (4), (COT)Ti[MeOC6H4C(NSiMe3)2)(THF) (5) and (COT)Ti[Ph2P(NSiMe3)2](6) have been prepared by treatment of [(COT)Ti(mu-Cl)(THF)]2 (1) with the corresponding heteroallylic ligands.
