ENERGY EFFICIENT SYNTHESIS OF BORANES

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 BCI₃, the B-H compound is B₂H₆, and where the reducing potential is provided electrochemically or by the thermolysis of formate.
