Synthesis and Evaluation of Silicon‐Containing Acridine Photocatalysts

A protocol for the synthesis of sterically hindered 9‐silylacridines via lithiation/silylation sequence is developed. The photocatalytic efficiency of obtained acridines is tested in a variety of decarboxylative processes and compared with the properties of aryl‐ and alkyl‐substituted analogs. To explain the observations, quantum chemical calculations are carried out, revealing the features of the spatial structures of these molecules.
