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.
