Abstract

Reaction of ansa-cyclopentadienyl pyrrolyl ligand (C5H5) CH2 (2-C4H3NH)(2) with Ti (NMe2) 4 affords bis (dimethylamido) titanium complex [(η5-C5H4) CH2 (2-C4H3N)] Ti (NMe2) 2 (3) via amine elimination. A cyclopentadiene ligand with two pendant pyrrolyl arms, a mixture of 1, 3-and 1, 4-{CH2 (2-C4H3NH)} 2C5H4 (4), undergoes an analogous reaction with Ti (NMe2) 4 to give [1, 3-{CH2 (2-C4H3N)} 2 (η5-C5H3)] Ti (NMe2)(5). ...
