Synthesis of a tin-functionalized cyclopentadiene derivative
摘要:
A 3-tert-butyl-1-(stannylpropyl)-functionalized cyclopentadienyl ligand precursor 6 is readily available in 64% overall yield from allylic alcohol 1 by a three-step reaction sequence including Pd-catalyzed hydrostannylation with Ph3SnH. Treatment with FeCl2 and ZrCl4 (.) 2THF afforded corresponding ferrocene and zirconocene derivatives. Transmetallation of Sn-Ph with Li-Bu was observed under these reaction conditions by using BuLi as a base. (C) 2004 Elsevier B.V. All rights reserved.
