midinato−imido complexes [Ti(NBut)(4-C6H4R)C(NSiMe3)2}Cl(py)2] (R = H (1) or OMe (2)) are described. Thus, reaction of 1 or 2 with LiC5H5 gave the half-sandwich compounds [Ti(NBut)(4-C6H4R)C(NSiMe3)2}(η-C5H5)] (R = H (3) or OMe (4)). Reaction of 1 with LiCH2SiMe3 or LiCH(SiMe3)2 gave the 14-electron, first fully characterized group 4 imido−alkyl derivatives [Ti(NBut)PhC(NSiMe3)2}CH(R)SiMe3}(py)]

[(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.

Dimeric [(COT)Y(mu-O3SCF3)(THF)]2 (1) is introduced as a versatile starting material for new monocyclooctatetraenyl complexes of yttrium (COT = cyclooctatetraenyl(2-)). Treatment of 1 with pyrazolylborate anions yields the monomeric half-sandwich complexes (COT)Y(HBpz3) (2) and (COT)Y[HB(3,5-Me2pz)3] (3). The yttrium benzamidinates (COT)Y[MeOC6H4C(NSiMe3)2]THF (4) and (COT)Y[CF3C6H4C(NSiMe3)2](THF) (5) are prepared similarly. An yttrium phosphazene derivative, (COT)Y[Ph2P(NSiMe3)2](THF) (6) is obtained by treating 1 with Li[Ph2P(NSiMe3)2]. All new organoyttrium complexes have been fully characterized by elemental analyses and spectroscopic methods including Y-89 NMR spectrocopy.
