An approach for the synthesis of α‐aryl alkylphosphonates based on visible‐light photocatalytic Giese reaction of α‐aryl vinylphosphonates with aliphatic carboxylic acids has been successfully developed. This protocol tolerates a wide range of functional groups and shows broad substrate scope with regard to both the carboxylic acid and vinylphosphonate components. With sequential Giese/hydrolysis reactions

Alkyl-GeMe3 was proven to be an effective radicalprecursor under visible-light photocatalysis. The metalloid nature of Ge allows single-electron transfer (SET) at the neutral Ge center and leads to advantages in separation and derivatization.
在可见光光催化下,烷基-GeMe 3被证明是一种有效的自由基前体。Ge 的准金属性质允许在中性 Ge 中心进行单电子转移 (SET),并在分离和衍生化方面具有优势。
