Abstract

Abstract Image

The cross-coupling of benzylic carbonates with arylboronic acids gave the corresponding diarylmethanes in high yields by use of the palladium catalyst generated in situ from [Pd(η3-C3H5)Cl]2 and 1,5-bis(diphenylphosphino)pentane (DPPPent). The Suzuki−Miyaura reaction using DPPPent−palladium catalyst is applicable to syntheses of a broad range of functionalized diarylmethanes.
