ABSTRACT Halogen bond donors are recognized as electrophilic catalysts in reactions involving carbonyl compounds. This study describes an unexpected inhibition of the Knoevenagel condensation by catalyst. To elucidate intricacies mechanism, overall reaction order and rate constants were determined using 1 H NMR spectroscopy, further experiments with different nucleophiles conducted. The findings revealed that primary is attributed to a substantial acceleration side aldehyde methanolysis, which hinders formation final alkene product.
