| Abstract: | The reactions of trifluoro or bromodifluoro acetamides with aromatic aldehydes in the presence of thionyl chloride and trifluoromethylsulfonic acid were investigated. Compared with the procedure reported previously, the yields were improved greatly and the reaction conditions were much milder. Both intra‐ and intermolecular weak interactions were discussed in detail based on the X‐ray diffraction analysis of 3aa and 3ab . |
