CH activation-based transformation of naphthalenes to 3-iodo-2-naphthylboronic acid derivatives for use in iterative coupling synthesis of helical oligo(naphthalene-2,3-diyl)s
Oligo(naphthalene-2,3-diyl)s were synthesized by iterative cross-coupling of 1,8-diaminonaphthalene-modified 3-iodo- 2-naphthylboronic acids prepared from naphthalenes via Ircatalyzed CH borylation, Ru-catalyzed ortho-CH silylation directed by an anthrani
Anthranilamide-masked o-iodoarylboronic acids as coupling modules for iterative synthesis of ortho-linked oligoarenes
Anthranilamide (AAM)-masked o-iodoarylboronic acids were prepared from AAM-masked arylboronic acids via Rucatalyzed o-C-H silylation, followed by iododesilylation with ICl. The Suzuki-Miyaura coupling of AAM-masked o-haloarylboronic acids with arylboronic acids proceeded under ligandfree conditions. Oligo(o-phenylene)s and oligo(naphthalene-2,3-diyl)s were synthesized via iterative Suzuki-Miyaura coupling sequences.
