Abstract:
Potassium fluoride (KF)/montmorillonite (K10-MMT) nanostructure acts as an active heterogeneous base catalyst for Knovenagel condensation. Here we have described the catalytic activities of KF/K10 nanostructure in the condensation reaction of various substituted benzaldehydes with active methylene compound malononitrile under mild condition. The experimental results showed that the KF/K10 had high catalytic activity and it can be recycled without significant loss of activity. This practical and eco-friendly protocol provides a facile way to C-C bond formation under mild conditions.
