  Experimental design and the optimization of a polymer supported palladium complex for use in the Heck reaction

  摘要：

  Optimization of the Heck reaction of 4-bromoacetophenone with styrene by a polymer supported, sulfur-containing palladacycle, varying 6 factors at a total of 28 different levels, corresponding to 5760 different possibilities was undertaken. Conversion improved from 34%, with large observable leaching to 88% with no leaching. This was accomplished using a Design of Experiments approach facilitated by the Statistical Design Package, MODDE 7.0(TM). (C) 2004 Elsevier Ltd. All rights reserved.
