“…Other platform molecules such as itaconic acid and fumaric acid have demonstrated similar trends [ 163 – 165 ]. The material is also proving successful on other acid-catalysed transformations including alkylation and acetylation [ 166 ] and even for complex substrates such as the Ritter reaction [ 167 ]. It is unclear at present why the increased porosity improves catalytic performance, though a likely explanation is that it is to similar reasons for the adsorption properties; increased pore volume leads to more exposed acidic sites.…”

With crude oil reserves dwindling, the hunt for a sustainable alternative feedstock for fuels and materials for our society continues to expand. The biorefinery concept has enjoyed both a surge in popularity and also vocal opposition to the idea of diverting food-grade land and crops for this purpose. The idea of using the inevitable wastes arising from biomass processing, particularly farming and food production, is, therefore, gaining more attention as the feedstock for the biorefinery. For the three main components of biomass—carbohydrates, lipids, and proteins—there are long-established processes for using some of these by-products. However, the recent advances in chemical technologies are expanding both the feedstocks available for processing and the products that be obtained. Herein, this review presents some of the more recent developments in processing these molecules for green materials, as well as case studies that bring these technologies and materials together into final products for applied usage.

“…[7][8][9] Over the last few decades, significant progress with catalysed Ritter reactions has been achieved. 10,11 In this reaction, an acidcatalysed nucleophilic addition of a nitrile to a carbenium ion, followed by hydrolysis generates an amide. Molecular rearrangements may occur if the intermediate carbonium ions isomerise to more stable structures.…”

“…Molecular rearrangements may occur if the intermediate carbonium ions isomerise to more stable structures. [7][8][9][10][11][12] However, to the best of our knowledge, there are few reports concerning the synthesis of amides via Ritter reactions. 7,11 In continuation of our previous work on p-menthane derivatives synthesised from turpentine via a cationic resincatalysed hydration reaction, 13 we envisioned a novel skeletal rearrangement Ritter reaction.…”
