Highly Reduced Metal Carbonyl Anions: Synthesis, Characterization, and Chemical Properties

摘要: Publisher Summary This chapter discusses highly reduced metal–carbonyl anions. In the unusually effective reducing medium of sodium-hexamethylphosphoramide (HMPA), [Mn(CO) 5 ] – underwent facile reduction to form a golden yellow brown solution. It is often important use solutions rather than slurries trianion salts minimize formation side products during reactions these materials with electrophiles. Infrared spectra Na 3 [M(CO) 4 as in HMPA or mineral oil mulls solid are quite similar terms peak positions. Protonation 3– and most known [Re(CO) examined. Perhaps persuasive chemical evidence for existence monohydrides manganese rhenium their high-yield conversion corresponding dihydrides, which can be isolated relatively stable crystalline solids. The tricesium salt was obtained an orange–brown powder trirubidium compound red–brown shiny microcrystalline substance. especially prone violent decomposition when they even gently scraped off fritted glass disk metal spatula. One very obvious limitation this reductive labilization method that ligand expelled should not susceptible either coordinated free state.
