In der Reaktion von 3‐Methyl‐ bzw. 1,3‐Dimethylindol (1a,1b) sind mit den Arylaldehyden 2 unter salzsaurer Katalyse die Methane 6 und 7 in glatter Reaktion zugänglich. Zwischenprodukte des Reaktionsweges zu 6 und 7 sind nur an einem Beispiel über eine Solvolyse‐Reaktion isolierbar. Die Struktureigenschaften der Methane 6 und 7 werden erstmals NMR‐spektroskopisch beschrieben.
The Lewis acid–surfactant–SiO2-combined (LASSC) nanocatalyst synthesizes BIMs, and has the advantages of being non-toxic, multi-cycle, highly stable and efficient.

A compound based on 2,2'-bis(indolyl)methane containing nitro group was studied as a new anion receptor. It could recognize selectively F- by an increasing fluorescence signal and a visible color change from colorless to blue. The introduction of nitro group induced the spectral dual-function related to the deprotonation of N-H protons. (C) 2015 Elsevier B.V. All rights reserved.
