TL;DR: In this article, the authors review recent developments for the generation of new carbon-carbon and carbon-heteroatom bonds mediated by agro-waste extracts and show that these aqueous extracts have great applicability in several transformations, including condensations, oxidations, multicomponent and coupling reactions.
Abstract: Agro-waste extracts are considered green solvents since they are easy to handle, readily accessible from natural waste feedstock, biodegradable and recyclable. Therefore, the employment of these extracts in reaction media has emerged as the most useful and eco-friendly alternative in modern organic chemistry. Here, we review recent developments for the generation of new carbon–carbon and carbon–heteroatom bonds mediated by agro-waste extracts. We show that these aqueous extracts have great applicability in several transformations, including condensations, oxidations, multicomponent and coupling reactions. The challenges and advantages on the use of water of agro-waste extracts in synthetic methodologies is also detail.

TL;DR: In this article , two different solids, chitosan/cellulose film and corn stem biochar, were investigated as catalytic supports of palladium nanoparticles in the Suzuki-Miyaura reaction.
Abstract: The production of sustainable catalytic supports for palladium nanoparticles is always desired, even more so through the recovery of biomass residues. In this sense, two different solids were investigated — chitosan/cellulose film and corn stem biochar — as catalytic supports of palladium nanoparticles. The solids were carefully characterized and tested in the Suzuki-Miyaura reaction, a typical cross-coupling reaction. The developed catalytic systems proved to be efficient and sustainable, promoted the formation of target products very well, and demanded green reactants under environmentally appropriate conditions. With the results shown in the manuscript, it is expected to contribute to the valorization of biomass and agro-industrial residues in the development of new catalysts for the chemical industry.
