Rhodium-Catalyzed Synthesis of Germoles via the Activation of Carbon–Germanium Bonds TobisuMamoru BabaKatsuaki ChataniNaoto 2011 The rhodium-catalyzed reaction of 2-germylphenylboronic esters with alkynes in the presence of a rhodium(I) catalyst is established as a modular method for the synthesis of an array of benzogermole derivatives. The reaction proceeds through the activation of C(sp<sup>3</sup>)–Ge bonds. The mechanism of this new bond activation process is discussed based on the activation aptitude of alkyl and aryl substituents on germanium.
