    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.

    摘要： The reaction of halo-boron compounds (B—X compounds, compounds having one or more boron-halogen bonds) with silanes provides boranes (B—H compounds, compounds having one or more B—H bonds) and halosilanes. Inorganic hydrides, such as surface-bound silane hydrides (Si—H) react with B—X compounds to form B—H compounds and surface-bound halosilanes. The surface bound halosilanes are converted back to surface-bound silanes electrochemically. Halo-boron compounds react with stannanes (tin compounds having a Sn—H bond) to form boranes and halostannanes (tin compounds having a Sn—X bond). The halostannanes are converted back to stannanes electrochemically or by the thermolysis of Sn-formate compounds. When the halo-boron compound is BCl3, the B—H compound is B2H6, and where the reducing potential is provided electrochemically or by the thermolysis of formate.

    摘要： A process for producing phosphonate esters containing the 2-(pyridyl)ethyl group by reacting a vinylpyridine with a di- or trihydrocarbylphosphite in the presence of a selected silane, protic acid, or Lewis acid is disclosed. Also disclosed are novel silylphosphonate esters containing the 2-(pyridyl)ethyl group. All of the compounds produced herein are useful as catalysts for increasing the molecular weight of polyamides.
