derivative. So far, no synthetic pathway has been found to avoid this intramolecular reaction. Herein we report the first general and external‐ligand‐free palladium‐catalyzed phosphination reaction that allows the synthesis of a wide variety of substituted ortho,ortho′‐bis(diphenylphosphino)biphenyls. With the aim of illustrating the scope and efficiency of this methodology, we applied it to the establishment

9-Silafluorenes via Base-Promoted Homolytic Aromatic Substitution (BHAS) – The Electron as a Catalyst

Transition-metal-free intramolecular radicalsilylation of 2-diphenylsilylbiaryls via base-promoted homolytic aromatic substitution (BHAS) to give 9-silafluorenes is reported. 2-Diphenylsilylbiaryls are readily prepared, and cross dehydrogenativesilylation occurs with tert-butylhydroperoxide (TBHP) as a cheap stoichiometric oxidant in the presence of a small amount of tetrabutylammonium iodide (TBAI)
