Zirconium hydride describes an alloy made by combining zirconium and hydrogen. Hydrogen acts as a hardening agent, preventing dislocations in the zirconium atom crystal lattice from sliding past one another. Varying the amount of hydrogen and the form of its presence in the zirconium hydride (precipitated phase) controls qualities such as the hardness, ductility, and tensile strength of the resulting zirconium hydride. Zirconium hydride with increased hydrogen content can be made harder and stronger than zirconium, but such zirconium hydride is also less ductile than zirconium. (Wikipedia).

15. Metals and Catalysis in Alkene Oxidation, Hydrogenation, Metathesis, and Polymerization
Freshman Organic Chemistry II (CHEM 125B) Alkenes may be oxidized to diols by permanganate or by OsO4 catalysis. Metal catalysts provide orbitals that allow simultaneous formation of two bonds from metal to alkene or H2. Coupling such oxidative additions to reductive eliminations, provi

Organometallic Reactions Part 4: Migratory Insertions
We've covered a few different types of organometallic reactions, so let's hit another. With migratory insertions, when two particular kinds of ligands are cis to one another, one can insert itself into the other metal-ligand bond. Reactions like hydrometalation and carbometalation qualify
