PhSeZn-halides (Santi's reagent) is a class of chemical compounds with general formula PhSeZnX (X = Cl, Br). This is the first example of bench stable zinc selenolates with a remarkable nucleophilic reactivity under on-water conditions. The synthesis and application of these reagents were first reported by Dr. Claudio Santi of the University of Perugia in 2008.[1] In 2016, the lead compound (PhSeZnCl) becomes commercially available.[2]
PhSeX + Zn → PhSeZnX[3]
