摘要
The synthesis of a new ligand system in which two amides are coupled via a rigid phenylene spacer is readily accomplished in a high-yield, single-step reaction. The dilithio salt (NO)2Li2(THF)x reacts with Ti(NR2)4 (R = Me, Et) to yield the titanium amides [(NO)2Ti(NR2)2]2. The latter react with excess Me3SiCl to produce the dichloride (NO)2TiCl2, which was also obtained by the reaction of [(NO)2Ti(NMe2)2]2 with TiCl4(THF)2 in refluxing toluene, and in a lower-yielding route, by salt metathesis between the dilithio salt and TiCl4(THF)2.
