Chavhan DM, Kodape MM, Patil SS, Gawhale ND


Abstract

Amines, naphthols and phenols are acylated using anhydrides by dissolving them in an aqueous medium containing catalytic ammount of calcinated egg Shell (CES). The present methodology is a green chemical process as the reactions is in a aqueous medium, convenient, efficient and environmentally benign with easy isolation of products and use of heterogeneous catalyst in aqueous medium. Allylation of 7-hydroxy-4-methyl-2H-chromen-2-one yields 7-(allyloxy)-4-methyl-2H-chromen-2-one catalysed by CES in polyethyleneglycol and allyl bromide.
