  Programming of microwave-assisted synthesis of new isophthalate derivatives using ZrOCl2 as a catalyst under solvent-free condition by experimental design

  摘要：

  In this investigation, isophthalate derivatives were prepared by the reaction of isophthaloyl dichloride with various alcohol derivatives using ZrOCl2 as an efficient, green and a heterogeneous catalyst under microwave irradiation and solvent-free condition. Optimization of the reaction condition was studied by the response surface method (Box Behnken Design (BBD)) with three replicates at a central point for developing a second order model. Predicting response values using the obtained model were in a good accordance with the experimental results. Clean reaction, easy workup procedure, the reusability of the catalyst, short reaction times and high yields were some advantages of this work. (C) 2014 Published by Elsevier B.V.

  An N‐heterocyclic carbene (NHC), generated by cathodic reduction of BMIm BF4, mediates the oxidative esterification of aromatic aldehydes with organic bromides in the corresponding ionic liquid as solvent. The product recovery by simple extractive work‐up with diethyl ether allowed the ionic liquid to be recycled up to 9 times for subsequent electrolyses, with no significant loss in the product yield
