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.
