reaction opens the first transition metal catalytic route for the preparation of this class of organogermanes, which are useful reagents for organic synthesis. The mechanism elucidated by NMR spectroscopic study of stoichiometric reactions shows that this process is a new catalytic activation of an sp-hybridized C−H bond involving the previously discovered activation of the C−Ge bond.
groups from commercially available reagents. More than 25 compounds were obtained and spectroscopically characterized. Moreover, detailed DFT calculations were performed to study the mechanism of the catalytic cycle of the germylative coupling. The results confirm our assumptions that the rate-determining step of the germylative coupling process is the product-formation step.
