Abstract

A series of reactions of phenyltriethoxysilane 1a (0.6 mmol) with 2a (0.5 mmol) were performed under several conditions for optimization studies. This coupling work was achieved with the aid of an aqueous base analogous to the Suzuki-Miyaura reaction. [1] In the presence of PdCl 2 (MeCN) 2 (0.015 mmol) and an aqueous solution of hydroxide ion (1.5 mmol) as an accelerating additive, the reaction in dioxane (2 mL) gave the desired biaryl 3 in 78-94% yields along ...
