Abstract

Acid-base bifunctional activity governed by -NH(2) group's microenvironment is evident from two different catalysts scrutinized by interchanging the location of -SO(3)H/NH(2) groups on periodic mesoporous ethylenesilica. The hydrophobic local environment plays a significant role in one-pot deacetalization/nitroaldol condensation.
