Leucoemeraldine-Base-Catalyzed Knoevenagel Condensation

Abstract

A facile method for Knoevenagel condensation has been developed by using Leucoemeraldine base as catalyst to give substituted alkenes in excellent yields. The recycling of the solid catalyst was investigated.

Keywords:

• Catalysis
• Knoevenagel condensation
• Leucoemeraldine base

Notes

^a All the products gave melting points and spectral data consistent with the reported data.^{[ 8 , 9 ]}

^b Isolated yield after recycling of catalyst.
