Microwave-Assisted Solvent-Free Cyclotrimerization of Enaminones to 1,3,5-Trisubstituted Benzenes Using Amberlite IR-120H as a Recyclable Heterogeneous Catalyst
Abstract 1,3,5-Trisubstituted benzenes are a valuable class of aromatic compounds that function as key motifs in drug design, rigid scaffolds in supramolecular chemistry, and important chromophores in advanced materials. However, constructing these densely substituted benzene frameworks through C−C bond formation remai...
