  A straight forward in situ preparation of NHC-substituted phosphapalladacycles

  摘要：

  A new simple technique for the preparation of NHC-substituted phosphapalladacycles is reported by using phosphapalladacycle acetate precursors and azolium tetrafluoroborate salts in DMSO. The one-pot synthesis avoids multi-step reactions employing free carbenes. With this technique, NHC-substituted phosphapallaclacycles were thus obtained that are not accessible via the free carbene route. (c) 2006 Elsevier B.V. All rights reserved.

  The preparation of unsaturated NHC-substituted phosphitepalladacycles via phosphitepalladacycle acetato and chloro precursors and azoliurn salts with non-coordinating anions in DMSO is reported. With this one-pot synthesis NHC-substituted phosphitepalladacycles are obtained avoiding multi-step reactions. The molecular structures of an acetate-bridged phosphitepalladacycle dimer, an unsaturated NHC-substituted palladacyclic complex and one acetylacetonato phosphapalladacycle complex have been determined by single-crystal X-ray analysis.
