Suzuki-Miyaura Cross-Coupling of Brominated 2,1-Borazaronaphthalenes with Potassium Alkenyltrifluoroborates

Conditions have been developed for the palladium-catalyzed cross-coupling of 3-bromo-2,1-borazaronaphthalenes with potassium alkenyltrifluoroborates. Twenty-seven alkenyl-substituted azaborines have been synthesized through this method, providing access to a family of 2,1-borazaronaphthalenes with alkenyl substitution at the C3 position.
