摘要：

Tetrakis(dimethylamino)zirconium (3a) and -hafnium (3b) react with cyclopentadiene-indene ligand precusors to form new eta(5):eta(5)- metallocenes 1c,d of the amido-type. A cyclopentadiene-fluorene ligand eliminates only one amide ligand from 3a to yield a tris(amide) complex 5, with the fluorenyl ligand not coordinating to the metal.
