Suitable transformation of compounds present in biomass using heteropolycompounds as catalysts

Heteropolycompounds, especially heteropolyacids, have received important attention as solid acid catalysts in recent decades. They have a strong Bronsted acidity and redox properties that make them important for the study of transformations of industrial and academic interest. To go toward suitable synthesis, heterogeneous catalysts are currently being developed, with especial focus on these materials. The design of catalysts for biomass conversion entails important challenges from the point of view of carbohydrate feedstock complexity and to develop environmentally friendly methods. This minireview aims to illustrate a number of very recent examples that show the significant potential of the heteropolycompounds in feedstock valorization and the transformation of some building blocks in multicomponent reactions.
