Methyl groups as widespread Lewis bases in noncovalent interactions
Nature Communications, 2021 Tetrel bonds are noncovalent interactions between electron donors and group 14 elements; in these situations, C(sp3) atoms can act as Lewis acids, accepting electron density.

Primary Productivity Was Limited by Electron Donors Prior to the Advent of Oxygenic Photosynthesis
Journal of Geophysical Research: Biogeosciences, 2019 To evaluate productivity on the early Earth before the advent of oxygenic photosynthesis, we integrated estimates of net primary production by early anaerobic metabolisms as limited by geological fluxes of key electron donor compounds, phosphate, and ...

Coordinating Electron Transport Chains to an Electron Donor
Organic Letters, 2015 Two electron transport chains (2 and 3) featuring two fullerenes with different electron acceptor strengths have been synthesized, characterized, and coordinated to a light harvesting/electron donating zinc porphyrin. Electrochemical assays corroborate the redox gradients along the designed electron transport chains, and complementary absorption and ...

npj Clean Water, 2022 The lack of electron donors in oxygen-rich aquatic environments limits the ability of natural denitrification to remove excess nitrate, leading to eutrophication of aquatic ecosystems. Herein, we demonstrate that electron-rich substances in river or lake

Synthesis of Organic Super-Electron-Donors by Reaction of Nitrous Oxide with N-Heterocyclic Olefins.
Journal of the American Chemical Society, 2019 The reaction of nitrous oxide (N2O) with N-heterocyclic olefins (NHOs) results in cleavage of the N-O bond and formation of azo-bridged NHO dimers. The latter represent very electron-rich compounds with a low ionization energy. Cyclic voltammetry studies
