the origin of chemoselectivity in the palladium‐catalyzed reactions of 2‐(dimethylphenylsilyl)phenyl triflates with or without an amino group at the 3‐position. The selective formation of a 5,10‐dihydrophenazasiline rather than a dibenzosilole from the substrate with an amino group at the 3‐position could be successfully explained by proposing a new 1,5‐palladium migration pathway that involves a neutral

Si−Si bonds is an important transformation in organic synthesis. Herein, we present a unified electrochemical strategy for the efficient and selective synthesis of disilanes, oligosilanes, and cyclosilanes—which are important precursors for the synthesis of functional organic and polymeric compounds—from readily available chlorosilanes.
