  • Lignin contains both C–O and C–C bonds, where C–C bonds are highly resistant to cleavage. Now, a bifunctional catalyst enables the cleavage of the challenging C–C bonds in lignin to produce biofuels.

  • The valorization of lignin is generally implemented through the cleavage of labile C–O bonds to produce aromatic monomers in up to 40 wt% yield. The remaining material consists of lignin dimers and oligomers connected by C–C bonds, but now a method has been developed for the oxidative cleavage of these C–C bonds using oxoammonium salts, to produce benzoquinones.

  • Despite numerous techniques for lignin depolymerization into mixtures of valuable monomers, methods for their upgrading into final products are scarce. Here the authors present an alternative approach whereby the target monomers are selectively and directly converted in unpurified mixtures into easily separable bisphenols and butene-2 under mild conditions.

  • Water is a standing challenge in the chemical modification of cellulose nanofibrils. Here, authors employ oxime-ligation to solve this by direct covalent chemistry on dialdehyde-CNF in water and assess the material for potential applications in green electronics and triboelectric nanogenerators.
