(RC 5 H 4 )TiCl 3 (1a, R=H; 1b, R=CH 3 ) 与 Li{NH(t-Bu)} 在 THF 中反应,得到 (RC 5 H 5 )TiCl 2 {NH(t-Bu)) (2a, R=H; 2b, R=CH3),分离产率为 80-90%。对湿气敏感的红橙色化合物可以从CH 2 Cl 2 /己烷混合物中结晶。确定了两种化合物的 X 射线结构,发现它们相似。
Reaction of (RC 5 H 4 )TiCl 3 (1a, R=H; 1b, R=CH 3 ) with Li{NH(t-Bu)} in THF affords (RC 5 H 5 )TiCl 2 {NH(t-Bu)) (2a, R=H; 2b, R=CH3) in 80-90% isolated yields. The moisture-sensitive red-orange compounds can becrystallized from CH 2 Cl 2 /hexane mixtures. The X-ray structures for the two compounds were determined and found to be similar.
