Abstract

The Suzuki-Miyaura cross-coupling reaction between a diborylmethane derivative and allyl halides or benzyl halides proceeded efficiently in the presence of an appropriate Pd-catalyst at room temperature. The present approach provides functionalized homoallylboronates and alkylboronates with excellent regio- and chemoselectivities.
