Herein, we report a commercially available natural saponin acting as a surfactant and serving as a micellar catalyst, enabling Suzuki–Miyaura cross-coupling effectively with highly challenging heteroaromatic substrates in water at room temperature.

A range of biaryl compounds (aryl−aryl, aryl−heteroaryl, and heteroaryl−heteroaryl) can be efficiently prepared by a palladium-catalyzed cross-coupling reaction between ortho-substituted triarylindium reagents and aryl halides. The triarylindium reagents are prepared by directed ortho-lithiation and transmetallation to indium from the corresponding benzene derivatives using various directed metallation
