The direct borylation reactions of two types of alpha-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.
