ReCl(CO)5-catalyzed Reactions of Aromatic Compounds with 1,3,5-Trioxane or Aqueous Formaldehyde Affording Diarylmethanes
Abstract
ReCl(CO)5 catalyzed the dehydration reaction of aromatic compounds with 1,3,5-trioxane or aqueous formaldehyde (37 wt%) under air. The reactions of a variety of aromatic compounds bearing electron-donating group(s) with 1,3,5-trioxane afforded the corresponding diarylmethanes in moderate to good yields.
