Sustainable Iron Catalysis for Chemodivergent Oxidation of Lignin‐Based Vanillyl Alcohol: Selective Access to Vanillin and Vanillic Acid

European Journal of Organic Chemistry, EarlyView.
Green reaction media enable chemodivergent oxidation of vanillyl alcohol, selectively affording vanillin or its fully oxidized counterpart, vanillic acid. The use of an earth‐abundant, inexpensive, and nontoxic iron catalyst for the transformation of lignin‐derived alcohol to fine chemicals underscores the sustainability of the process. A low E‐factor (

Inconsistent Transcriptomic Responses to Hexabromocyclododecane in Japanese Quail: A Comparative Analysis of Results From Four Different Study Designs

Environmental Toxicology and Chemistry, EarlyView.
Abstract Efforts to use transcriptomics for toxicity testing have classically relied on the assumption that chemicals consistently produce characteristic transcriptomic signatures that are reflective of their mechanism of action. However, the degree to which transcriptomic responses are conserved across different test methodologies has seldom been ...
