Reducing agents can be ranked by increasing strength by ranking their reduction potentials. Reducers donate electrons to (that is, "reduce") oxidizing agents, which are said to "be reduced by" the reducer. The reducing agent is stronger when it has a more negative reduction potential and weaker when it has a more positive reduction potential.
The central metal (usually B vs Al) strongly influences reducing agent's strength. Aluminum hydrides are more nucleophilic and better reducing agents relative to borohydrides. [5] The relatively weak reducer sodium borohydride is typically used for reducing ketones and aldehydes. It tolerates many functional groups (nitro group, nitrile, ester ...
TCEP is often used as a reducing agent to break disulfide bonds within and between proteins as a preparatory step for gel electrophoresis.. Compared to the other two most common agents used for this purpose (dithiothreitol and β-mercaptoethanol), TCEP has the advantages of being odorless, a more powerful reducing agent, an irreversible reducing agent (in the sense that TCEP does not ...
Organic redox reactions: the Birch reduction. Organic reductions or organic oxidations or organic redox reactions are redox reactions that take place with organic compounds.In organic chemistry oxidations and reductions are different from ordinary redox reactions, because many reactions carry the name but do not actually involve electron transfer.

One method of generation of AgNPs is the reduction of the raw material, silver nitrate, to elemental silver using a reducing agent such as trisodium citrate. AgNPs are synthesized using microwave irradiation , [ 4 ] gamma irradiation [ 6 ] UV activation, [ 7 ] or conventional heating [ 8 ] of the precursor silver nitrate, AgNO 3 using an ...
The scheme depicts the mechanism for the Leuckart reaction using formamide as the reducing agent. Formamide first nucleophilically attacks the carbonyl carbon. The oxygen is protonated by abstracting hydrogen from the nitrogen atom, subsequently forming a water molecule that leaves, forming N-formyl derivative, which is resonance stabilized. [3]
Ethylene glycol protects a ketone (as an acetal) during an ester reduction, vs. unprotected reduction to a diol. A protecting group or protective group is introduced into a molecule by chemical modification of a functional group to obtain chemoselectivity in a subsequent chemical reaction.
The reason for the increased monodispersity when using NaBH 4 is that it is a stronger reducing agent than citrate. The impact of reducing agent strength can be seen by inspecting a LaMer diagram which describes the nucleation and growth of nanoparticles. [21] When silver nitrate (AgNO 3) is reduced by a weak reducing agent like citrate, the ...
