Organocatalytic Application of Ionic Liquids: [bmim][MeSO4] as a Recyclable Organocatalyst in the Multicomponent Reaction for the Preparation of Dihydropyrimidinones and -thiones
substitution in the latter. The ionic liquid can be recovered and reused for five consecutive reactions without significant loss of catalytic efficiency. The applicability of the methodology for large-scale reaction highlights its potential for bulk synthesis. ionic liquid - organocatalyst - multicomponent reaction - dihydropyrimidinone - dihydropyrimidinethione

1′ exhibits excellent catalytic activity for the condensation–cyclization reaction between 2-benzoyl pyridine and different benzylamines via oxidativeamination of the C(sp3)–Hbond to form 1,3-diarylated imidazo[1,5-a]pyridines under mild aerobicconditions. In addition to this, 1′ shows excellent heterogeneous catalytic activity in Biginelli reactions. The solid catalyst could be recycled several
Chemoselective Multicomponent Condensation of 1,3-Cyclohexanedione, Urea or Thiourea with Aldehydes: One-Pot Synthesis of Two Families of Fused Heterobicyclic and Spiro-fused Heterobicyclic Aliphatic Rings
organometallic catalyst including polymeric imidazolium ionic liquid-functionalized Mn(III) Schiffbasecomplex (PIL-SB-Mn(III)) was prepared and characterized using various analyses like FTIR, H-NMR, FE-SEM, EDX, TGA, and ICP-OES. Then, the applications of catalyst were tested in the synthesis of 3,4-dihydropyrimidine-2(1H)-one/thiones under solvent-free conditions. This polymeric ionic liquid catalyst can carry
