Natural organic matter plays an important role in oceanic hydrothermal systems through a
combination of geological and chemical processes. However, identifying the hydrothermal …

Alcohol dehydration by elimination of water is central to a series of functional group
interconversions that have been proposed as a reaction pathway that connects …

The biogenic elements, H, C, N, O, P and S, have a long cosmic history, whose evolution
can still be observed in diverse locales of the known universe, from interstellar clouds of gas …

Hydrothermal systems provide a unique habitat for the subsurface biosphere, and possibly,
for the origin of life. Amides are fundamental to hydrothermal organic geochemistry and …

Amide bonds are fundamental products in biochemistry, forming peptides critical to protein
formation, but amide bonds are also detected in sterile environments and abiotic synthesis …

One-pot transition-metal-free synthesis of aromatic aldehydes and ketones via oxidative
decarboxylation of arylacetic acids in water is developed. Protocol relies on the direct …

Mechanistic interpretations of how organic reactions happen can enhance the predictive
capacity of models for geochemical transformations built on thermodynamic and kinetic …

Examples of anaerobic oxidation of aldehydes in hydrothermal solutions are reported. The
reaction using iron (III) nitrate as the oxidant occurs under mild hydrothermal conditions and …

Aldehydes represent an intermediate redox state of organic carbon and can be precursors to
carboxylic acids via disproportionation. A model aldehyde, benzaldehyde, was subjected to …

Hydrothermal organic transformations occurring in geochemical processes are influenced
by the surrounding environments including rocks and minerals. This work is focused on the …
