Efficiency Enhancement of a Photocatalytic Decarbonylation of an Aminocyclopropenone by Benzothiophene Substitution was written by Mishiro, Kenji;Nomura, Mitsuki;Furuyama, Taniyuki;Kunishima, Munetaka. And the article was included in Journal of Organic Chemistry in 2021.Application of 638-02-8 The following contents are mentioned in the article:

To improve the efficiency of the photocatalytic decarbonylation of cyclopropenones, the effects of substituents on cyclopropenone were explored. A benzothiophene-substituted aminocyclopropenone exhibited significantly improved decarbonylation efficiency to produce the corresponding ynamine, which worked as a potent dehydration condensation agent. The benzothiophene derivative was applicable to the photocatalytic reaction in the presence of potential excited-state quenchers such as oxygen and anilines. The high catalyst sensitivity would be attributed to the involvement of triplet energy transfer reaction pathway, which was not observed in the reaction with previously reported aminocyclopropenones. This study involved multiple reactions and reactants, such as 2,5-Dimethylthiophene (cas: 638-02-8Application of 638-02-8).

Semi-empirical estimation of ion-specific cross sections in electron ionization of molecules was written by Irikura, Karl K.. And the article was included in Journal of Chemical Physics in 2016.Recommanded Product: 2,5-Dimethylthiophene The following contents are mentioned in the article:

Partial ionization cross sections are the absolute yields of specific ions from an electron-mol. collision. They are necessary for modeling plasmas and determining the sensitivity of mass spectrometers, among other applications. They can be predicted semi-empirically when exptl. data are available for channel-specific oscillator strengths. However, such data are seldom available because they are obtained using specialized apparatus Here, an alternative semi-empirical method is proposed that exploits exptl. data obtained using ordinary mass spectrometers, as corrected for mass discrimination. Data are presented for an incident electron energy of 70 eV. (c) 2016 American Institute of Physics.
