A photocatalytic and sustainable production of vicinal diols from benzylic alcohols through the selective formation of a carbon–carbon bond is developed under visible light irradiation. Typically, a 92.2% conversion of benzyl alcohol with a 92.9% selectivity of hydrobenzoin is achieved using a heterogeneous modified ZnIn₂S₄ catalyst at room temperature. This smart catalyst can extend the life of the benzyl alcohol radical to more than 24 ns and avoid the generation of benzaldehyde in the reaction system due to its excellent ability of separating photogenerated carrier and inhibiting the recombination of electron–hole pairs.

可见光驱动的选择性碳-碳键形成，用于生产邻位二醇

在可见光照射下，通过选择性形成碳-碳键，从苄醇中光催化和可持续生产邻位二醇。通常，在室温下使用多相改性的ZnIn ₂ S ₄催化剂可实现苯甲醇的92.2％转化率和氢安息香选择性92.9％。这种智能催化剂可将苯甲醇自由基的寿命延长至24 ns以上，并且由于其出色的分离光生载流子和抑制电子-空穴对重组的能力，可避免在反应系统中生成苯甲醛。
