Ch15 : Oxidation of Alcohols

Oxidation of Alcohols Reaction type: Oxidation-Reduction Summary Common reagents: The outcome of oxidation reactions of alcohols depends on the substituents on the carbinol carbon In order for each oxidation step to occur there must be H on the carbinol carbon Primary alcohols can be oxidised to aldehydes or further to carboxylic acids In aqueous media the

Dimethyldicarbonate Reaction with Higher Alcohols

Dimethyldicarbonate (DMDC) is a sterilant proposed for use on wine immediately before bottling for the prevention of fermentation by yeast The major breakdown products of DMDC in wine are carbon dioxide and methanol primarily from hydrolysis Earlier work has shown DMDC to react with ethanol and ammonia to form small amounts of residual by-products

Reactions of unsaturated fatty alcohols XV

Apparently dipentene serves as an effective chain transfer agent during styrenation keeps the growing polymer chains short and reduces crosslinking reactions The amount and type of unsaturation needed in the fatty side chains of the polymer to produce homogeneous products were studied Ultraviolet and infrared analyses were useful in determining the function of unsaturation in these reactions

Gold‐ and Silver‐Catalyzed Reactions of Propargylic

Propargylic alcohols bearing an adjacent electron‐rich aryl group can also undergo silver‐catalyzed substitution of the alcohol with oxygen nitrogen and carbon nucleophiles This latter reaction was initially observed with a batch of gold catalyst that was probably contaminated with small quantities of silver salt

2 Properties of alcohols

Alcohols turns from liquid to solid at room temperature and pressure (rtp) as the length of the hydrocarbon chain in the alcohol increases The boiling points of the first 11 alcohols are as follows: The factors affecting the boiling/melting points of alcohols are not only hydrogen bonds but also van der Waals dispersion forces and dipole-dipole interactions

(ii) Reaction involving cleavage of C-O bond in alcohols In these reactions the reactivity order of different alcohols : Alkyl group due to +1 effect increases the electron density on the carbon and oxygen atom of C-OH bond As a result the bond cleavage becomes easy Greater the number of alkyl groups present more will be the reactivity of alcohol Thus the relative order
