Nickel boride is widely used as a catalyst in organic chemistry

Overview of nickel boride Ni2B powder

Nickel boride is a common name for materials mainly composed of nickel and boron, and is widely used as a catalyst in organic chemistry. Their approximate chemical composition is Ni2.5B, and they are often incorrectly expressed as "Ni2B" in organic chemistry publications.

The nickel boride catalyst is usually prepared by reacting a nickel salt with sodium borohydride. The ingredients and properties vary depending on the specific preparation method. The two most common forms described and evaluated in detail by Herbert C. Brown and Charles Allan Brown in 1963 are called P-1 nickel and P-2 nickel.

These catalysts are usually obtained in the form of black particles (P-1) or colloidal suspensions (P-2). They are air-stable, non-magnetic and non-pyrophoric, but slowly react with water to form nickel hydroxide Ni(OH)

They are insoluble in all solvents, but will react with concentrated mineral acids. They are said to be more effective hydrogenation catalysts than Raney nickel.

Application of Nickel Boride Ni2B Powder

The nickel boride Ni2B catalyst is prepared by reacting nickel chloride and nickel chloride with a borohydride reagent (such as NaBH4 of sodium borohydride). It can be used for selective hydrogenation reaction, desulfurization reaction, dehalogenation reaction, hydrolysis reaction and reduction reaction of functional groups such as nitro group.

The nickel boride Ni2B catalyst prepared by the reaction of NiCl2 and NaBH4 can also be used for the desulfurization reaction. Compared with the Raney nickel catalyst used in the traditional desulfurization reaction, a higher yield can be obtained, and the disadvantages of Raney nickel, such as strong alkali, flammability, and sensitivity to air and moisture, are avoided.

In addition, thioamides, sulfides and sulfides can all be desulfurized under the catalysis of nickel boride to obtain corresponding hydrocarbons. In the presence of nickel boride, primary, secondary and tertiary aliphatic nitro compounds can be reduced to amines.

The combination of NiCl2/NaBH4 can also achieve dehalogenation and hydrolysis reactions, reducing many α-bromoketones to ketones, or dibromoketones to alkenes, and benzyl, allyl and propargyl esters to the corresponding alkanes. .
