Calix[n]arene sulfonic acids bearing pendant aliphatic chains as recyclable surfactant-type Bronsted acid catalysts for allylic alkylation with allyl alcohols in water

xlink.rsc.org | Mar 20, 2008

Calix[n]arene sulfonic acids bearing pendant aliphatic chains were developed as surfactant-type Brønsted acid catalysts for allylic alkylation with allyl alcohols in water. The allylic alkylation products of aromatic compounds were obtained in 60 94% yields.
