Palladium-Catalyzed Hiyama Cross-Coupling of Aryltrifluorosilanes with Aryl and Heteroaryl Chlorides
摘要:
An efficient, palladium-catalyzed Hiyama cross-coupling reaction of aryltrifluorosilanes with aryl chlorides has been developed. A wide variety of functionalized biaryl derivatives were isolated in good to excellent yields. The scope of this reaction has also been extended to heteroaryl chlorides, affording the corresponding heterobiaryl compounds in high yields.

An intramolecularhydrosilylation strategy was developed for the asymmetric synthesis of chiral monohydrosilanes. This protocol is suitable for the synthesis of dihydrobenzosilole-, tetrahydrobenzosiline- and oxatetrahydrobenzosiline-based monohydrosilanes with excellent diastereo-, regio-, and enantioselectivities. Notably, the catalyst loading could be reduced to 0.1 mol %.
