  Reaction of [Ga2(tBu)4(neol-H)]2 with early transition metal chlorides and amides

  摘要：

  The reaction of [Ga-2(Bu-t)(4)(neol-H)(2)] (neol-H-2 = 2,2-dimethylpropane-1,3-diol) with TiCl4, ZrCl4, or VCl4 in the presence of proton sponge, C10H6(NMe2)(2), yields [(Bu-t)GaCl3][C10H6(NMe2)(2)H] (1). The reaction of [Ga-2(Bu-t)(4)(neol-H)(2)] with M(NMe2)(4) (M = Ti, Zr) in yields [(Bu-t)(2)Ga(mu-NMe2)](2) (2) along with multiple transition metal containing products. In contrast, Cr(NEt2)(4) reacts with [Ga-2(Bu-t)(4)(neol-H)(2)] to yield [Ga-3(Bu-t)(5)(neol)(2)]. For the reaction with Ti(NMe2)(4), the identity of the titanium containing products have been determined as [(Bu-t)(2)Ga(neol)(2)Ti(NMe2)] (3), [Ti(NMe2)(2)(neol)(2)] (4) and [Ti(neol)(2)] (5). In addition, following the reaction by H-1 NMR allows for the observation of an additional gallium containing intermediate, [(Bu-t)(2)Ga(neol)(2)](2)Ti(NMe2)(2) (6) and [(Bu-t)(2)Ga](2)(mu-neol) (7). Compounds 4 and 5 are also made by the direct reaction of Ti(NMe2)(4) with neol-H-2. Reaction of Ga(Bu-t)(3) with HNMe2 yields (Bu-t)(3)Ga(HNMe2) (8). Compound 2 is also formed along with [Ti(NMe2)(2)((OPr)-Pr-i)(2)] (9) from the reaction of [(Bu-t)(2)Ga(mu-(OPr)-Pr-i)](2) with Ti(NMe2)(4). The formation of compound 6 is implied by the isolation of the hydration product, [(Bu-t)(2)Ga(neol)(2)Ti(mu-O)Ga(Bu-t)(HNMe2)] (10). The reaction of CpTi(NMe2)(3) with [(Bu-t)(2)Ga(neol-H)](2) yields [(Bu-t)(2)Ga(neol)(2)TiCp] (11) and 2. (C) 2002 Elsevier Science Ltd. All rights reserved.
