Abstract
Abstract Recently there has been great interest in the reactivity of transition‐metal (TM) centers towards white phosphorus (P 4 ). This has ultimately been motivated by a desire to find TM‐mediated alternatives to the current industrial routes used to transform P 4 into myriad useful P‐containing products, which are typically indirect, wasteful, and highly hazardous. Such a TM‐mediated process can be divided into two steps: activation of P 4 to generate a polyphosphorus complex TM‐P n , and subsequent functionalization of this complex to release the desired phosphorus‐containing product. The former step has by now become well established, allowing the isolation of many different TM‐P n products. In contrast, productive functionalization of these complexes has proven extremely challenging and has been achieved only in a relative handful of cases. In this review we provide a comprehensive summary of successful TM‐P n functionalization reactions, where TM‐P n must be accessible by reaction of a TM precursor with P 4 . We hope that this will provide a useful resource for continuing efforts that are working towards this highly challenging goal of modern synthetic chemistry.
