solution, the bis-ligated chiral titanium amides (1)2Ti(NMe2)2 (6), (2)2Ti(NMe2)2 (8), (3)2Ti(NMe2)2 (10), and zirconium amides (1)2Zr(NMe2)2 (7), (2)2Zr(NMe2)2 (9), (3)2Zr(NMe2)2 (11), respectively, in good yields. Under similar reaction conditions, treatment of M(NMe2)4 with 2 equiv. of Schiff base ligands 4H or 5H gives, after recrystallization from a toluene solution, the chiral bis-ligated titanium
