A new insight into ortho-(dimesitylboryl)diphenylphosphines: applications in Pd-catalyzed Suzuki-Miyaura couplings and evidence for secondary π-interaction. | LitMetric

AI Article Synopsis

  • Ortho-(Dimesitylboryl)phenylphosphines 1 and 2 were used in palladium-catalyzed Suzuki-Miyaura carbon-carbon coupling reactions.
  • The research involved coordination studies to understand how the structure of these compounds affects their reactivity in these reactions.
  • A new coordination mode was discovered for phosphine-arylboranes, which includes a unique secondary π-interaction between a mesityl group on boron and the palladium metal center.

Article Abstract

ortho-(Dimesitylboryl)phenylphosphines 1 and 2 were applied in Pd-catalyzed Suzuki-Miyaura C-C couplings. Coordination studies were performed in order to rationalize the relationship between structure and reactivity. Full characterization of a Pd(0) complex derived from 1 has evidenced a new coordination mode for phosphine-arylboranes involving secondary π-interaction between one of the mesityl groups at boron and the metal centre.
