Reactivity of a Substituted Aryloxenium Cation with a Triplet Ground State

Chemistry – A European Journal, Volume 31, Issue 58, October 16, 2025.
A substituted aryloxenium cation with a triplet electronic ground state is not a strong electrophile like the analogous singlet aryloxenium cations. It undergoes only radical reactions that are remarkably fast for a delocalized π‐type biradical. Abstract Aryloxenium cations contain a formally positively charged, monovalent oxygen atom. In spite of this

From Anti‐Van't Hoff Le Bel Molecules of C6NH to Astronomically Relevant and Experimentally Known and Unknown Carbenes

ChemPhysChem, Volume 26, Issue 20, October 15, 2025.
Molecules with a planar tetracoordinate carbon atom serve as reactive intermediates for carbenes. While isomer 2 has been identified in the laboratory, isomer 5 remains elusive to date. Here, four stationary points with a planar tetracoordinate carbon (ptC) atom that are considered as anti‐van't Hoff Le Bel molecules have been computationally ...

Relative Velocities between 13CO Structures within 12CO Molecular Clouds

The Astronomical Journal
Velocity fields of molecular clouds (MCs) can provide crucial information on the merger and split between clouds, as well as their internal kinematics and maintenance, energy injection and redistribution, and even star formation within clouds.

Regarding the Detection of Interstellar C4 and C5 Molecules

The Astrophysical Journal
Analysis of very high signal-to-noise ratio (S/N) spectra of reddened stars allowed us to determine an upper limit (UL) of the column density N (C _4 ).

Formation of All Three C2H4O Isomers—Ethylene Oxide (c-C2H4O), Acetaldehyde (CH3CHO), and Vinyl Alcohol (CH2CHOH)—in Ethanol-containing Interstellar Analog Ices

The Astrophysical Journal
Oxygen-containing complex organic molecules are key precursors to biorelevant compounds fundamental for the origins of life. However, the untangling of their interstellar formation mechanisms has just scratched the surface, especially for oxygen ...
