Preparation and application of nickel boride

Overview of nickel boride Ni2B powder

Nickel boride is a chemical compound of nickel and boron, and its molecular formula is Ni2B. It is one of the borides of nickel. The formula "Ni2B" and the name "nickel boride" are generally used for nickel-boron catalysts obtained by reacting a nickel salt with sodium borohydride. 

Nickel boride catalysts can reduce unsaturated ethers, alcohols, aldehydes, esters, amines and amides to corresponding saturated compounds without hydrogenation. Unsaturated nitriles can be reduced to primary amines, while the epoxide remains unchanged. In addition to sodium borohydride, dimethoxyborane (Meo) 2BH4 or lithium borohydride LiBH4 can also be reacted with nickel chloride to obtain a nickel boride catalyst for this type of reaction. It is worth emphasizing that only NiCl2 exhibits catalytic activity in the combined catalytic reduction of 2-methylquinoline with various transition metal salts (such as CoCl2, NiCl2, CuCl2, CrCl3 and sodium borohydride). 

How is nickel boride Ni2B powder produced?

Nickel boride Ni2B (along with other nickel borides) can be obtained by heating sodium borohydride and powdered nickel metal to 670°C in an airtight container, thereby generating a pressure of up to 3.4 MPa for the released hydrogen. The main reaction can be summarized as

2NaBH4 + 2NaH + B2H6

2Ni + 2B2H6 + NaH + Ni2B + 3BH3 + 2H2 + Na,

However, other reactions occur to form other borides.

Application of Nickel Boride Ni2B Powder

The nickel boride catalyst is prepared by reacting nickel chloride NiCl2 with a borohydride reagent (such as sodium borohydride NaBH4). It can be used for selective hydrogenation reaction, desulfurization reaction, dehalogenation reaction, hydrolysis reaction and reduction of nitro group and other functional groups.

The nickel boride 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, higher yield can be obtained, and the shortcomings of Raney nickel such as strong alkali, flammability, and sensitivity to air and moisture can be 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 reducing benzyl, allyl and propargyl esters to The corresponding alkanes.
