which mainly solves the technical problems of low yield, unstable quality, and complicated operation in the existing synthesis process. In this invention, N-benzyl-hydroxylamine hydrochloride and 1,4-dibromobutane are used as raw materials, sodium hydride as a base, and tetrahydrofuran as a solvent ...

Metal hydrides are metals which have been bonded to hydrogen to form a new compound. Any hydrogen compound that is bonded to anothermetal elementcan effectively be called a metal hydride. Generally, the bond is covalent in nature, but some hydrides are formed from ionic bonds. The hydrogen has...
