Microwave accelerated, Ni/C-catalyzed cross-couplings of in situ-derived zirconocenes
摘要:
Both vinyl and alkyl zirconocenes undergo rapid couplings with aryl halides under heterogeneous conditions in a microwave reactor using Ni/C as catalyst. Ligand variations both in type and stoichiometry play major roles in the extent of conversion. (C) 2003 Elsevier Ltd. All rights reserved.
