The Effect of Cluster Size on the Intra-Cluster Ionic Polymerization Process

open access: yesMolecules, 2021
Polyaromatic hydrocarbons (PAHs) are widespread in the interstellar medium (ISM). The abundance and relevance of PAHs call for a clear understanding of their formation mechanisms, which, to date, have not been completely deciphered.

Diverse synthesis of C2-linked functionalized molecules via molecular glue strategy with acetylene

open access: yesNature Communications, 2022
Although acetylene is an ideal two-carbon building block, very few catalytic methods can be applied to incorporate acetylene into fine chemicals. Here, the authors show photoredox-catalyzed syntheses of C2- linked molecules with gaseous acetylene under ...

Free Radical Isomerizations in Acetylene Bromoboration Reaction

open access: yesMolecules, 2021
The experimentally motivated question of the acetylene bromoboration mechanism was addressed in order to suggest possible radical isomerization pathways for the syn-adduct.

Diamond films from combustion of methyl acetylene and propadiene [PDF]

open access: yes, 1995
To date diamond films grown with the combustion technique have used either acetylene or, rarely, ethylene as the fuel. However, there are barriers to large scale commercialization of the combustion technique using either fuel.

Terminal and Internal Alkyne Complexes and Azide-Alkyne Cycloaddition Chemistry of Copper(I) Supported by a Fluorinated Bis(pyrazolyl)borate

open access: yesMolecules, 2021
Copper plays an important role in alkyne coordination chemistry and transformations. This report describes the isolation and full characterization of a thermally stable, copper(I) acetylene complex using a highly fluorinated bis(pyrazolyl)borate ligand ...

Theoretical studies of a hydrogen abstraction tool for nanotechnology [PDF]

open access: yes, 1991
In the design of a nanoscale, site-specific hydrogen abstraction tool, the authors suggest the use of an alkynyl radical tip. Using ab initio quantum-chemistry techniques including electron correlation they model the abstraction of hydrogen from ...

FUNDAMENTALS FOR PREVENTING ACETYLENE COMBUSTION AND DETONATION IN EQUIPMENT [PDF]

open access: yesАктуальные вопросы пожарной безопасности
The scientific and technical bases for ensuring fire and explosion safety in the handling of acetylene are considered. Safe operation with acetylene in the equipment can be ensured by localization of the combustion source by the following methods ...

Molecular Fragmentation of Acetylene by VUV Double Photoionization

open access: yesProceedings, 2017
Acetylene is a simple molecule of interest for interstellar medium (ISM) and planetary atmospheres. The presence of C2H2 was detected by IR spectroscopic measurements. Acetylene was also found as a minor component in the atmosphere of gas giants like the

Catalytic synthesis of acetone by direct hydration of acetylene [PDF]

open access: yesE3S Web of Conferences, 2023
Background: Replacing the cadmium–calcium phosphate catalyst with a zinc-containing catalyst makes it possible to obtain acetone in good yield with minor changes in technology.

Reactivity of the Indenyl Radical (C9 H7 ) with Acetylene (C2 H2 ) and Vinylacetylene (C4 H4 ). [PDF]

open access: yes, 2019
The reactions of the indenyl radicals with acetylene (C2 H2 ) and vinylacetylene (C4 H4 ) is studied in a hot chemical reactor coupled to synchrotron based vacuum ultraviolet ionization mass spectrometry.
