Crossed-molecular-beam study on the formation of phenylacetylene from phenyl radicals and acetylene.
During the last decades, polycyclic aromatic hydrocarbons (PAHs) and other related aromatic compounds, such as ionized PAHs, have received considerable attention from astronomers, astrobiologists, environmentalists, and the combustion community. In the interstellar medium, PAHlike species account for up to 10% of the cosmic carbon budget, have been suggested as carriers of both the unidentified...
متن کامل4-(Dimethylamino)phenyl phenyl ketone
In the crystal structure of the title compound, C(15)H(15)NO, the two benzene rings are twisted from each other by a dihedral angle of 47.97 (4)°. The crystal structure is stabilized by weak inter-molecular C-H⋯O and C-H⋯π inter-actions, and π-π inter-actions with a centroid-centroid distance of 3.8493 (5) Å are observed.
متن کاملHydrogen-Abstraction/Acetylene-Addition Exposed.
Polycyclic aromatic hydrocarbons (PAHs) are omnipresent in the interstellar medium (ISM) and also in carbonaceous meteorites (CM) such as Murchison. However, the basic reaction routes leading to the formation of even the simplest PAH-naphthalene (C10 H8 )-via the hydrogen-abstraction/acetylene-addition (HACA) mechanism still remain ambiguous. Here, by revealing the uncharted fundamental chemist...
متن کاملSingle-Acetylene Linked Porphyrin Nanorings
The synthesis of ethyne-linked porphyrin nanorings has been achieved by template-directed Sonogashira coupling. The cyclic hexamer and octamer are predicted by density functional theory to adopt low symmetry conformations, due to dihedral twists between neighboring porphyrin units, but their symmetries are effectively D6h and D8h, respectively, in solution by 1H NMR. The fluorescence spectra in...
متن کامل2-(Dimethylaminomethyl)phenyl phenyl telluride
The title compound, C(15)H(17)NTe, is a heteroleptic Te, N-bidentate ligand having a short Te⋯N contact [2.8079 (16) Å] involving a secondary bonding inter-action between the amino N and Te(II) atoms. The Te-C bond [2.136 (2) Å] trans to the amino group is slightly elongated compared to the other Te-C bond [2.1242 (18) Å] due to the hypervalent inter-action. The bond angle for the trans N-Te-C ...
