Synthesis and structure of ansa-cyclopentadienyl pyrrolyl titanium complexes: [(eta(5)-C5H4)CH2(2-C4H3N)]Ti(NMe2)(2) and [1,3-{CH2(2-C4H3N)}(2)(eta(5)-C5H3)]Ti(NMe2)

Reaction of ansa-cyclopentadienyl pyrrolyl ligand (C5H5)CH2(2-C4H3NH) (2) with Ti(NMe2)(4) affords bis(dimethylamido)titanium complex [(eta (5)-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)}(2)C5H4 (4), undergoes an analogous reaction with Ti(NMe2)(4) to give [1,3-{CH2(2-C4H3N)}(2)(eta (5)-C5H3)]Ti(NMe2) (5). Molecular structures of 3 and 5 have been determined by single crystal X-ray diffraction studies. (C) 2001 Elsevier Science B.V. All rights reserved.
