Mechanistic insights and atmospheric implications of the degradation reaction of 3-methoxy-1-propanol by reaction with hydroxyl radicals and identification of the end products in the presence of O2/NO

Scientific Reports
The study investigated the degradation of 3-methoxy-1-propanol (3M1P) by OH• using the M06-2X/6-311++G(d, p) level, with CCSD(T) single-point corrections. We focused on hydrogen atom abstraction from various alkyl groups within the molecule.

Struktur-Reaktivität-Gleichungen und ihre Anwendung zur Bestimmung organischer Reaktionsmechanismen

CHIMIA, 1973
Several examples of the application of structure-reactivity correlations to the determination of organic reaction mechanisms are discussed. As a first example, our results on the photochlorination of aliphatic compounds are considered.

Site-selective α-C(sp3)–H arylation of dialkylamines via hydrogen atom transfer catalysis-enabled radical aryl migration

Nature Communications
Site-selective C(sp3)–H arylation is an appealing strategy to synthesize complex arene structures but remains a challenge facing synthetic chemists. Here we report the use of photoredox-mediated hydrogen atom transfer (HAT) catalysis to accomplish the ...

Energy Transfer Catalysis Enabled 2,2,2‐Trifluoroethoxy‐Amination of Olefins

ChemistryEurope
A thioxanthone‐catalyzed 2,2,2‐trifluoroethoxyamination of olefins is developed via the formation of the corresponding alkoxy and iminyl radicals using unprecedented, easily prepared, and bench‐stable oxime ethers as bifunctional reagents.

Impact of the T296S mutation in P450 GcoA for aryl-O-demethylation: a QM/MM study

Frontiers in Chemistry
Lignin, a complex plant cell wall component, holds promise as a renewable aromatic carbon feedstock. p-Vanillin is a key product of lignin depolymerization and a precursor of protocatechuic acid (PCA) that has tremendous potential for biofuel production.
