The growing use of pyridine stabilized polycationic I(III) regents ([PhI(Pyr)₂]²⁺) as versatile oxidizing agents is reviewed. Currently the number of examples describing the use of these oxidants is modest, however those that do exist are spread across a diverse range of topic areas. The highly oxidizing nature of the [PhI(Pyr)₂]²⁺ polycations coupled with the potential for neutral ligand delivery to metal centers or in situ generation of the reactive [PhI]⁺ electrophile gives access to a range of novel transformations across topic areas including organic, heavy main-group centered and organometallic chemistry.

Weiss试剂：合成有用的一类碘（III）配位化合物

综述了吡啶稳定的聚阳离子I（III）试剂（[PhI（Pyr）₂ ] ²⁺）作为通用氧化剂的日益增长的应用。目前，描述使用这些氧化剂的例子数量不多，但是确实存在的例子分布在不同的主题领域。[PhI（Pyr）₂ ] ²⁺聚阳离子的高度氧化性质加上中性配体传递至金属中心或原位生成反应性[PhI] ⁺亲电试剂的潜力，使人们可以跨主题领域进行一系列新颖的转化包括有机，重的以主族为中心的化学和有机金属化学。
