摘要:
A family of neutral and cationic Ti(IV) complexes supported by the sterically demanding and trianionic ligand (O3N)(3-)(O3N3-(O3N3- = tris(2-0,3-Ad,5-tBubenzyl)amine, Ad = 1-adamantyl) have been prepared from the hydrolysis of TiCl4(THF)(2) with the free base (O3N)H-3 and excess NEt3, followed by anion exchange reactions. These (O3N)Ti+ cores are resistant to moisture and air, are mononuclear, and possess C-3 symmetry on the NMR timescale. (c) 2005 Elsevier B.V. All rights reserved.
