  Synthesis and Characterization of N-Heterocyclic Carbene Phospha-Palladacycles and Their Properties in Heck Catalysis

  摘要：

  Palladacycles are among the most active catalyst systems for the Mizoroki-Heck reaction to date. We present N-heterocyclic carbene (NHC) substituted phospha-palladacycles as a new class of catalysts. This new type of palladacycles combines the advantageous stability of phospha-palladacycles with the steric demand and high a-donor strength of N-heterocyclic carbenes. In this work NHC-substituted phospha-palladacycles are tested in Heck catalysis. The activity of these catalysts allows the coupling of even aryl chlorides in good yields.

  Acetylacetonates of phospha-palladacycles are new catalysts in the Heck coupling of aryl chlorides and bromides with styrene. Turnover numbers (TON) of much higher than 300,000 and product yields up to 99% are obtained. (c) 2005 Elsevier B.V. All rights reserved.
