A practical and mild synthesis of pentafluorophenoxy ketone in a continuous flow microfluidic reactor has been developed through 1,3-Dibromo-5,5-dimethylhydantoin (DBH)/DMSO mediated oxidative coupling of styrenes with pentafluorophenol. Moreover, a series of pentafluorophenoxy ketone products were provided in moderate to good yields under metal-free conditions. A magnifying continuous flow system was erected to verify the appliance of this method.

Cyclodehydration of α-phenoxy ketones promoted by Eaton’s reagent (phosphorus pentoxide–methanesulfonic acid) is used to prepare 3-substituted or 2,3-disubstituted benzofurans with moderate to excellent yields under mild conditions. The method provides a facile access to benzofurans from readily available starting materials such as phenols and α-bromo ketones. The reaction is highly efficient, which is attributed to the good reactivity and fluidity of Eaton’s reagent. The reaction can be applied to prepare naphthofurans, furanocoumarins, benzothiophenes, and benzopyrans.

Use of a scientific microwave apparatus for rapid optimization of reaction conditions in a monomode function and then substrate screening in a multimode function

Recently, a new apparatus has become available, which aims to bring together in one unit the advantages of a monomode and a multimode microwave device. We have assessed the applicability of the apparatus toward rapid optimization of reaction conditions in a monomode function and then substrate screening in a multimode function. We have also probed the effects of differences in microwave absorptivity of reaction mixtures on the product conversions in screening multiple substrates simultaneously in a multimode microwave apparatus. We find that when the microwave absorptivity of a reaction mixture is dictated by the solvent, there is little effect on the heating profile of varying the substrate in a screening run. However, this is not the case when reactions involving non-microwave absorbant solvents are used. In this case the characteristics of the substrate can affect significantly the outcome of the reaction.
A simple method for the preparation of aryl phenacyl ether in micellar medium: Part I
