Hard graft pays off for Henry : An efficient acid–base bifunctional mesoporous catalyst was prepared by one‐step post‐synthesis grafting of aminoorganoalkoxysilane groups on mesoporous silica (see picture). The catalyst led to yields of over 99 % in the Henry reaction (nitroaldol condensation) of p ‐hydroxybenzaldehyde and nitromethane to form nitrostyrene.
