Recent Advances on Cellulose Sulfuric Acid as Sustainable and Environmentally Benign Organocatalyst for Organic Transformations

Abstract

Cellulose sulfuric acid has proved its competence as a potential bio-compatible, non-toxic and inexpensive heterogeneous solid acid catalyst in synthetic organic chemistry. Owing to its remarkable properties such as non-hygroscopic nature, recyclability, superior catalytic activity and high stability it has been actively explored as an efficient and biodegradable organocatalyst in diverse chemical transformations of synthetic relevance. This review attempts to summarize a significant advancement and catalytic applications of cellulose sulfuric acid for the synthesis of plethora of biologically relevant organic molecules

Chlorosulfonic acid coated on porous organic polymer as a bifunctional catalyst for the one-pot three-component synthesis of 1,8-naphthyridines

“…3,4,[9][10][11] Today, there is increasing interest in the design and synthesis of heterogeneous supports containing high loads of sulfonic acid groups to increase the turnover number (TON) and turnover frequency (TOF) of the reaction. 12 Despite signicant advances in producing eco-friendly heterogeneous supports (such as cellulose, 13 silica, 14,15 carbon nanotubes, 16 iron aluminate spinel hercynite, 17 graphite carbon nitride, 18 magnetic nanoparticles, 4,5,7,[19][20][21] and polymers 22 ), it is necessary to set certain rules for their applications in terms of their synthesis, recycling, management, and cost.…”
