Abstract
Quaternary organic tetraalkylammonium hydroxide grafted on MCM-41 is a strong Brønsted base catalyst, and represents a useful alternative to soluble bases in reactions such as Knoevenagel condensations, Michael additions and aldol condensations because of their high catalytic activity under mild conditions, and good stability.Keywords
