Ferrocene labelled supported ionic liquid phase (SILP) containing organocatalytic anion for multi-component synthesis

Ferrocene labelled supported ionic liquid phase (SILP) catalyst containing l-prolinate anion has been synthesized by anion metathesis reactions of ionic liquid like unit grafted on Merrifield resin. The multi-component synthesis of 1-amidoalkyl-2-naphthols from 2-naphthol, aryl aldehydes and amides has been effectively achieved under solvent-free conditions using SILP catalyst. Additionally, the catalyst could be reused for several cycles with slight loss of activity.

Ferrocene labelled supported ionic liquid phase (SILP) catalyst containing l-prolinate anion has been synthesized. The SILP catalyst showed TON in the range of 1240–1740 and TOF in the range of 1.62–4.29 h−1 in the multi-component synthesis of 1-amidoalkyl-2-naphthols.Figure optionsDownload as PowerPoint slide
