Borylation on Benzo[1,2‑b:4,5‑b′]- and Naphtho[1,2‑b:5,6‑b′]dichalcogenophenes: Different Chalcogene Atom Effects on Borylation Reaction Depending on Fused Ring Structure

The direct borylation reactions of two types of α-silyl-protected acenedichalcogenophenes, i.e., benzo[1,2-b:4,5-b′]- and naphtho[1,2-b:5,6-b′]dichalcogenophenes, were examined, and it was observed that the reaction efficiency largely depends on the fused ring structure and chalcogenophene ring....
