Metal Cation-Exchanged Montmorillonite (M<sup><i>n</i>+</sup>-Mont)-Catalyzed Friedel–Crafts Acylation of 1-Methyl-1-cyclohexene and 1-Trimethylsilyl-1-alkynes
The acylation of 1-methyl-1-cyclohexene and 1-trimethylsilyl-1-alkynes with acyl chlorides has been investigated in the presence of a variety of metal cation-exchanged montmorillonites (abbreviated as Mn+-monts), where the catalysts are recyclable for several times after simple washing.
