由于乙腈的C-CN键难以断裂，因此使用乙腈作为氰化剂是一个挑战。在此，我们报道了一种温和的光辅助路线进行氰化过渡金属硝酸盐使用乙腈作为氰化剂加上室温C-C键断裂。DFT计算和实验观察表明，自由基参与的反应机制，其中排除了自由氰离子的毒性。
It is a challenge to use acetonitrile as a cyanating agent because of the difficulty in cleaving its C-CN bond. Herein, we report a mild photo-assisted route to conduct the cyanation of transition metal nitrates using acetonitrile as the cyanating agent coupled with room-temperature C-C bond cleavage. DFT calculations and experimental observations suggest a radical-involved reaction mechanism, which excludes toxicity from free cyanide ions.
