Abstract
- Naphthalene- and phenanthrene-fused [22]smaragdyrin BF <subscript>2</subscript> -complexes were synthesized by 1) Suzuki-Miyaura coupling of β-brominated [22]smaragdyrin BF <subscript>2</subscript> complexes with 2-formylarylboronates, 2) Witting-type methoxymethylenation of the formyl group, and 3) methanesulfonic acid-catalyzed cyclization reaction. Subsequently these BF <subscript>2</subscript> complexes were deboronized and oxidized to the corresponding antiaromatic [20]smaragdyrin free bases. The installed fused structures led to decrease of the aromatic characters of the [22]smaragdyrin BF <subscript>2</subscript> complexes and the antiaromatic characters of the [20]smaragdyrin free bases.<br /> (© 2023 Wiley-VCH GmbH.)
