摘要

硅研究支持我们的全氟烷基取代三苯胺（TPAs）丙酮敏化电环反应成全氟烷基取代咔唑的实验结果。计算结果表明，取代基通过改变电子密度分布，影响了TPAs在光诱导[6π]-电环化反应中的区域选择性和反应活性。更多信息可以在s.m.的研究文章中找到。Bonesi， A. Postigo及其同事（DOI: 10.1002/chem.202500133）。

Cover Feature: Syntheses of Carbazoles by Photosensitized Electrocyclization of Triarylamines. Effect of Inductive Electron-Withdrawing Groups on the Photocyclization (Chem. Eur. J. 22/2025)

In silico studies support the experimental findings of our acetone-sensitized electrocyclization reactions of perfluoroalkyl-substituted triphenylamines (TPAs) into perfluoroalkyl-substituted carbazoles. The calculations predicted that the substituents affect the regioselectivity and the reactivity of TPAs during the photoinduced [6π]-electrocyclization reaction due to changes in the electron density distributions. More information can be found in the Research Article by S. M. Bonesi, A. Postigo and co-workers (DOI: 10.1002/chem.202500133).

期刊介绍： Chemistry—A European Journal is a truly international journal with top quality contributions (2018 ISI Impact Factor: 5.16). It publishes a wide range of outstanding Reviews, Minireviews, Concepts, Full Papers, and Communications from all areas of chemistry and related fields. Based in Europe Chemistry—A European Journal provides an excellent platform for increasing the visibility of European chemistry as well as for featuring the best research from authors from around the world. All manuscripts are peer-reviewed, and electronic processing ensures accurate reproduction of text and data, plus short publication times. The Concepts section provides nonspecialist readers with a useful conceptual guide to unfamiliar areas and experts with new angles on familiar problems. Chemistry—A European Journal is published on behalf of ChemPubSoc Europe, a group of 16 national chemical societies from within Europe, and supported by the Asian Chemical Editorial Societies. The ChemPubSoc Europe family comprises: Angewandte Chemie, Chemistry—A European Journal, European Journal of Organic Chemistry, European Journal of Inorganic Chemistry, ChemPhysChem, ChemBioChem, ChemMedChem, ChemCatChem, ChemSusChem, ChemPlusChem, ChemElectroChem, and ChemistryOpen.
