This species is highly reactive and is attacked by the alcohol. Rearrangement give an alkoxysulfonium ylide which decomposes to give dimethyl sulfide and the carbonyl compound. This reaction has been largely displaced by the Swern oxidation, which also uses DMSO as an oxidant in the presence of an electrophilic activator. Swern oxidations tend ...
Under Corey–Kim conditions allylic and benzylic alcohols have a tendency to evolve to the corresponding allyl and benzyl chlorides unless the alcohol activation is very quickly followed by addition of triethylamine. In fact, Corey–Kim conditions —with no addition of triethylamine— are very efficient for the transformation of allylic and ...
The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks. The suffix -ol appears in the International Union of Pure and Applied Chemistry (IUPAC) chemical name of all substances where the hydroxyl group is the functional group with the ...
Under new rules coming into force next year, all alcohol products sold in Ireland face a legal requirement to carry health labelling, including warning of the links to cancer, liver disease and ...
The first example of an enantioselective nitroaldol reaction was reported in 1992 using Shibasaki catalysts. [11] One of the most frequently employed methods for inducing enantio- or diastereoselectivity in the Henry reaction is the use of chiral metal catalysts, in which the nitro group and carbonyl oxygen coordinate to a metal that is bound ...
The new American Association for Cancer Research report predicts more than 2 million new cancer cases diagnosed in 2024, and emphasizes the dangerous role played by alcohol use in cancer development.

Under ideal conditions the reaction produces 50% of both the alcohol and the carboxylic acid (it takes two aldehydes to produce one acid and one alcohol). [5] This can be economically viable if the products can be separated and both have a value; the commercial conversion of furfural into furfuryl alcohol and 2-furoic acid is an example of this ...
