Alcohol oxidation is a collection of oxidation reactions in organic chemistry that convert alcohols to aldehydes, ketones, carboxylic acids, and esters. The reaction mainly applies to primary and secondary alcohols. Secondary alcohols form ketones, while primary alcohols form aldehydes or carboxylic acids. [1] A variety of oxidants can be used.
2-Pentanol (IUPAC name: pentan-2-ol; also called sec-amyl alcohol) is an organic chemical compound.It is used as a solvent and an intermediate in the manufacturing of other chemicals. 2-Pentanol is a component of many mixtures of amyl alcohols sold industrially. 2-Pentanol is chiral and thus can be obtained as either of two stereoisomers designated as (R)-(−)-2-pentanol and (S)-(+)-2-pentanol.
The primary alcohols have general formulas RCH 2 OH. The simplest primary alcohol is methanol (CH 3 OH), for which R = H, and the next is ethanol, for which R = CH 3, the methyl group. Secondary alcohols are those of the form RR'CHOH, the simplest of which is 2-propanol (R = R' = CH 3). For the tertiary alcohols, the general form is RR'R"COH.
Hydroboration–oxidation reaction is a two-step hydration reaction that converts an alkene into an alcohol. [1] The process results in the syn addition of a hydrogen and a hydroxyl group where the double bond had been. Hydroboration–oxidation is an anti-Markovnikov reaction, with
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.

For oxidations to the aldehydes and ketones, two equivalents of chromic acid oxidize three equivalents of the alcohol: 2 HCrO 4 − + 3 RR'C(OH)H + 8 H + + 4 H 2 O → 2 [Cr(H 2 O) 6] 3+ + 3 RR'CO. For oxidation of primary alcohols to carboxylic acids, 4 equivalents of chromic acid oxidize 3 equivalents of the alcohol. The aldehyde is an ...
[1] [2] Mechanism of one type of carbonyl addition hydrogen auto-transfer reaction involving hydrometalation (step 2). [ 3 ] Hydrogen auto-transfer , also known as borrowing hydrogen , is the activation of a chemical reaction by temporary transfer of two hydrogen atoms from the reactant to a catalyst and return of those hydrogen atoms back to a ...
2R 3 C−H + O 2 → 2 R 3 C−OH R 3 C−H + O 2 + 2e − + 2H + → R 3 C−OH + H 2 O. Since O 2 itself is a slow and unselective hydroxylating agent, catalysts are required to accelerate the pace of the process and to introduce selectivity. [1] Hydroxylation is often the first step in the degradation of organic compounds in air.
