Regioselective formation of [2 (η5 cyclopentadienyl) 2 fluorenylpropane] titanium complexes: precursors, synthesis, structure and reactivity

When an NMR tube containing a solution of cis-I in wet benzene-dr 0.01% H.,O was allowed to stand for i week, yellow crystals formed, which were identified as

Method B afforded 2e in a 55% yield the reaction mixture was stirred for 6 h at room temperature Mp 110-112 °C dec yellow powder, EtOAc.. Acknowledgements This research was supported

The related tantalum complex [Tag5-C5Me5{g5-C5H4SiMe2CH2CH@ CH2}NtBuCl] 11 was isolated as a brown waxy solid in 70% yield by a similar reaction of the corresponding

A similar alkylation of the zirconium complex 3 with the lithium derivative of the bulkier neophyl group led to the trineophyl complex 8, isolated in 90% yield as a yellow oil at
