BOOTSTRAP SYNTHESIS OF BORANES

摘要

Metal hydride materials react with BZ₃ compounds in the presence of ligand to form BH₃-L compounds. A compound of the formula HBZ₂ is prepared from a compound of the formula BZ₃ by reacting a first amount of a compound of the formula HBZ₂ with a metal hydride material "MH" and a compound "L" to form a material of the formula BH₃-L, and then reacting the BH₃-L thus formed with a compound of the formula BZ₃ to form HBZ₂ in a second amount greater than the first amount of HBZ₂. 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 HBZ₂ 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 BH₃-L material.
