Observation of different reactivities of para and ortho-water towards trapped diazenylium ions [PDF]

open access: yesNature Communications, 2018
Water is one of the most fundamental molecules in chemistry, biology and astrophysics. It exists as two distinct nuclear-spin isomers, para- and ortho-water, which do not interconvert in isolated molecules.

Micelle formation of tetradecyltrimethylammonium X‐benzoate surfactants: Benzoate counterion substituent effects

open access: yesJournal of Surfactants and Detergents, Volume 27, Issue 2, Page 259-267, March 2024.
Abstract Tetradecyltrimethylammonium (TTA+) benzoate surfactants have a range of CMC values dependent on the substituent effects of the benzoate counterions. Twenty‐three TTA+/X‐benzoate CMC values were determined by conductivity and surface tension. The 12 TTA+/para‐ and meta‐benzoate and the unsubstituted benzoate CMC values yield a correlation to ...

The etherase system of Novosphingobium sp. MBES04 functions as a sensor of lignin fragments through phenylpropanone production to induce specific transcriptional responses

open access: yesEnvironmental Microbiology Reports, Volume 16, Issue 1, February 2024.
Novosphingobium sp. MBES04 possesses a unique ability to sense lignin fragments by producing phenylpropanones which induce specific transcriptional responses. The strongly induced clusters involved in energy production by oxidative degradation and multidrug resistance. This adaptation may be a survival strategy, whereby the strain MBES04 preferentially

Sulfenamide-enabled ortho thiolation of aryl iodides via palladium/norbornene cooperative catalysis

open access: yesNature Communications, 2019
Poly-substituted aromatic sulfur compounds are widely found in pharmaceuticals, agrochemicals and organic materials. However, the position that a sulfur moiety can be introduced to is largely restricted to a pre-functionalized site; otherwise, use of ...

Hydrogen Bond Directed ortho‐Selective C−H Borylation of Secondary Aromatic Amides

open access: yesAngewandte Chemie, 2019
Reported is an iridium catalyst for ortho‐selective C−H borylation of challenging secondary aromatic amide substrates, and the regioselectivity is controlled by hydrogen‐bond interactions.
