A method for preparing a compound of the formula BH3-L from a compound of the formula BZ3, comprising:

• reacting a first amount of a compound of the formula HBZ2 with an metal hydride material and a compound “L” to form a material of the formula s BH3-L, wherein Z comprises alkoxy, aryloxy, amido, arylamido, or mixtures thereof, wherein two Z comprises doubly-substituted alkoxy, doubly-substituted aryloxy, doubly-substituted amido, doubly substituted arylamido, alkoxy-amido, or aryloxy-arylamido, wherein the compound “L” comprises ethers, aromatic ethers, amines, aromatic amines, heterocyclic nitrogen compounds, sulfides, aromatic sulfides, and heterocyclic sulfur compounds, and
• reacting a portion of the BH3-L thus formed with an amount of compound of the formula BZ3 to form a second amount of HBZ2, wherein the amount of BZ3 is chosen such that the second amount of HBZ2 and the first amount of HBZ2 are about the same amount.

A method of forming BH3-L where L is ammonia or amine, comprising:

• reacting HBZ2 with a compound “X” that promotes a disproportionation of HBZ2 to a BH3-X compound;
• and thereafter
• reacting the BH3-X compound with a compound “L” comprising ammonia or amine to form BH3-L, wherein L comprises ammonia or amine, and wherein Z comprises alkoxy, aryloxy, amido, arylamido, wherein two Z comprises doubly-substituted alkoxy, doubly-substituted aryloxy, doubly-substituted amido, doubly substituted arylamido, alkoxy-amido, or aryloxy-arylamido.

A method of forming BH3-ammonia, comprising:

• reacting a first amount of a compound of the formula HBZ2 with an metal hydride material “MH” and a compound “L” to form a material of the formula BH3-L, wherein Z comprises alkoxy, aryloxy, amido, arylamido, or mixtures thereof, wherein two Z comprises doubly-substituted alkoxy, doubly-substituted aryloxy, doubly-substituted amido, doubly substituted arylamido, alkoxy-amido, or aryloxy-arylamido, wherein compound “L” comprises ethers, aromatic ethers, amines, aromatic amines, heterocyclic nitrogen compounds, sulfides, aromatic sulfides, or heterocyclic sulfur compounds,
• reacting a portion of the BH3-L thus formed with an amount of compound of the formula BZ3 to form a second amount of HBZ2, wherein the amount of BZ3 is chosen such that the second amount of HBZ2 and the first amount of HBZ2 are about the same amount, and
• reacting the remaining BH3-L with ammonia to make BH3-ammonia.

A method for preparing a compound of the formula BH3-L, comprising:

• reacting a compound of the formula HBZ2 with a metal hydride material “MH” and a compound “L”, wherein Z comprises alkoxy, aryloxy, amido, arylamido, or mixtures thereof, wherein two Z comprises doubly-substituted alkoxy, doubly-substituted aryloxy, doubly-substituted amido, doubly substituted arylamido, alkoxy-amido, or aryloxy-arylamido, wherein compound “L” comprises ethers, aromatic ethers, amines, aromatic amines, heterocyclic nitrogen compounds, sulfides, aromatic sulfides, or heterocyclic sulfur compounds.
