Mechanochemical Hydrodeoxygenations

European Journal of Organic Chemistry, EarlyView.
A silver‐catalyzed mechanochemical hydrodeoxygenation with triethylsilane as reductant allows to convert ketones to the corresponding methylene derivatives in good yields after a short reaction time. Selected examples show that also alcohols, ethers, and sulfoxides can react. In this work, a mechanochemical hydrodeoxygenation (HDO) was developed. Using

By‐product of heparin extraction as a sustainable alternative to enhance the use of nitrogen in agriculture

Environmental Progress &Sustainable Energy, EarlyView.
Abstract This study evaluates the potential of a new organic fertilizer derived from porcine intestinal mucosa (designated BHE), a by‐product of the heparin extraction process, as a sustainable nitrogen (N) source for agriculture. The work was conducted in two stages: (i) chemical and spectroscopic characterization of BHE compared with poultry litter ...
