Selective Degradation of Lignosulfonate and Lignin with Periodate to 5‐Iodovanillin (Adv. Sustainable Syst. 4/2022)

Sustainable Chemistry The cover image for article number 2100391 by Siegfried R. Waldvogel and co-workers represents a method to obtain selectively 5-iodovanillin, as an advanced building block, from side-stream lignins by degradation using electrochemically generated periodate. In times of climate changes the utilization of lignin as renewable feedstock for fine chemicals is considered, and would rival petroleum refining.
