  摘要：

  Bis(trimethylsilyl)amino-(2,2,5,5-tetramethyl-1,2,5-azadisila-cyclopent-1-yl)-titanium dichloride (3) and bis(2,2,5,5-tetramethyl-1,2,5-azadisila-cyclopent-1-yl)-titanium dichloride (4) were prepared and converted into the di(1-alkynyl)titanium derivatives, (Me3Si)(2)N[(CH2Me2Si)(2)N]Ti(Cequivalent toC-R)(2) (5) and [(CH2Me2Si)(2)N](2)Ti(Cequivalent toC-R)(2) (6) [R = Me (a), Ph (b), SiMe3 (c)]. The reaction of 5a and 5b with trialkylboranes such as Et,B leads almost quantitatively to titana-2,4-cyclopentadienes 7a and 7b, in which a diethylboryl group functions as a substituent in 3-position. In the same manner, 6b reacts with Et3B or Pr3B to titana-2,4-cyclopentadienes 8b or 9b, respectively. It is proposed that these reactions proceed by 1,1-alkylboration. Compound 5c also reacts with Et3B, however, a complex mixture was obtained. All products were characterised by H-1-, B-11-, C-13-, N-15- and Si-29-NMR spectroscopy. (C) 2002 Elsevier Science B.V.
