Metal cation-exchanged montmorillonite (Mn+-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 recycla
