Metal hydride materials react with BZ<SUB>3 </SUB>compounds in the presence of ligand to form BH<SUB>3</SUB>-L compounds. A compound of the formula HBZ<SUB>2 </SUB>is prepared from a compound of the formula BZ<SUB>3 </SUB>by reacting a first amount of a compound of the formula HBZ<SUB>2 </SUB>with a metal hydride material "MH" and a compound "L" to form a material of the formula BH<SUB>3</SUB>-L, and then reacting the BH<SUB>3</SUB>-L thus formed with a compound of the formula BZ<SUB>3 </SUB>to form HBZ<SUB>2 </SUB>in a second amount greater than the first amount of HBZ<SUB>2</SUB>. Z is selected from alkoxy, aryloxy, amido, arylamido, doubly substituted alkoxy, doubly substituted aryloxy, doubly substituted amido, doubly substituted arylamido, alkoxy-amido, and aryloxy-arylamido. When Z is bidentate, then HBZ<SUB>2 </SUB>has a ring structure. "L" is selected from ethers, aromatic ethers, amines, aromatic amines, heterocyclic nitrogen compounds, sulfides, aromatic sulfides, and heterocyclic sulfur compounds. "L" becomes a ligand in the BH<SUB>3</SUB>-L material.
