Hydrogen gas is a reducing agent when it reacts with non-metals and an oxidizing agent when it reacts with metals. 2 Li (s) + H 2(g) → 2 LiH (s) [ a ] Hydrogen (whose reduction potential is 0.0) acts as an oxidizing agent because it accepts an electron donation from the reducing agent lithium (whose reduction potential is -3.04), which causes ...

Lithium borohydride (LiBH 4) is a borohydride and known in organic synthesis as a reducing agent for esters.Although less common than the related sodium borohydride, the lithium salt offers some advantages, being a stronger reducing agent and highly soluble in ethers, whilst remaining safer to handle than lithium aluminium hydride.
Commonly referred to as LiTEBH or Superhydride, it is a powerful reducing agent used in organometallic and organic chemistry. It is a colorless or white liquid but is typically marketed and used as a THF solution. [2] The related reducing agent sodium triethylborohydride is commercially available as toluene solutions.
Stoichiometric reducing agents to accomplish this task include lithium aluminium hydride, sodium borohydride, alkoxy borohydrides, alkoxy aluminium hydrides, and boranes. Although stoichiometric chiral reducing agents often afford products with high enantioselectivity, the necessity of a stoichiometric amount of chiral material is a disadvantage.
Sodium metal is a one-electron reducing agent. Four equivalents of sodium are required to fully reduce each ester, although two more equivalents are typically consumed in deprotonating the product alcohols to alkoxides. Ethanol serves as a proton source. [1] The reaction produces sodium alkoxides, according to the following stoichiometry:
MAID is currently legal in 10 states and Washington, D.C., but eight other states are considering similar laws this year.
With a reduction potential near −2.5 V vs NHE, the naphthalene radical anion is a strong reducing agent. [1] It is capable of defluorinating PTFE and is commonly used for chemically etching PTFE to allow adhesion. [7]
