概要

• 論文の詳細を見る

• Treatment of octadehydrotribenzo[14]annulene ([14]DBA) with bromine or iodine gave the corresponding tetrahalo-substituted benzodiindenocyclooctatetraenes selectively via tandem twofold transannular bond formations. The exclusive mode of cyclization in contrast to that observed for the nucleophile-induced cyclizations is interpreted in terms of the relative stabilities of the key intermediates in both processes.
