Nickel Boride

Introduction

Nickel boride (Ni₂B), first reported in the pioneering work of Schlezinger and Brown [¹] and traditionally used as a catalyst for hydrogenation, [²] has more recently found a niche as a reducing agent in its own right. [³] Its ease of preparation, handling, and versatility as a reducing agent promise nickel boride its deserved attention from academic and industrial sectors. Nickel boride has been employed for a wide range of transformations including reductive dehalogenation of organic halides [4] , reductive amination of carbonyl compounds, [5] desulfurization of a variety of thioxo compounds, [6] deoxygenation of sulfoxides and selenoxides, [7] and reducing of nitrogen functionalities. [8] Of late, the reagent is being explored in the form of a nickel boride silica nanocomposite catalyst for hydrogen production from NaBH₄ hydrolysis. [9]
