simple copper‐catalyzed alkyl–alkynyl cross‐coupling strategy has been developed using the reaction between alkynyl bromides and alkylzirconocenes. The alkylzirconocenes were generated in situ via regioselective addition of Schwartz's reagent (ZrCp2HCl) on to alkenes. The reaction has a broad scope, a range of functionalized bromoalkynes and alkylzirconium reagents were successfully coupled, resulting in

Several allyl-functionalized dendrimers and mono-functional model compounds have been prepared. These have been hydro-zirconated using [Cp2ZrHCl](x) to give zirconocene terminated dendrimers. These dendrimers have been characterized using spectroscopic techniques. particularly NMR. (C) 2004 Elsevier B.V. All rights reserved.
