Lecture – Alexandre Gagnon

Organobismuth compounds are organometallic species that contain one or multiple C–Bi bonds and that are easily prepared from inexpensive and low-toxic inorganic bismuth salts. Organobismuth compounds show unique reactivities which are modulated by the oxidation state of the bismuth center, the net charge of the compound, the number of coordinated groups, the ability to form hypercoordinating interactions, the dual behavior of bismuth as a classic pnictogen and a metal, and the high tolerance towards functional groups. Organobismuth species have been abundantly used in a wide diversity of metal-catalyzed reactions, enabling the facile construction of C–C, C–N, C–O and C–S bonds. This presentation will show our work on the development of metal-catalyzed arylation and cyclopropylation reactions using organobismuth compounds.
