Hypoiodite-catalyzed regioselective oxidation of alkenes: An expeditious access to aldehydes in aqueous micellar media

A highly anti-Markovnikov selective oxidation of alkenes based on in situ generated hypoiodite catalysis in aqueous micellar media under mild conditions has been described. This novel catalytic system realizes an efficient synthesis of aldehydes from alkenes in an economically viable and environmentally safe fashion. The preliminary mechanistic studies suggest that the reaction proceeds via tandem iodofunctionalization/1,2-aryl or alkyl migration. The scope and limitations of this tandem process are demonstrated with various mono- and disubstituted (terminal and internal) olefins.

Efficient and highly aldehyde selective wacker oxidation

A method for efficient and aldehyde-selective Wacker oxidation of aryl-substituted olefins using PdCl2(MeCN)2, 1,4-benzoquinone, and t-BuOH in air is described. Up to a 96% yield of aldehyde can be obtained, and up to 99% selectivity can be achieved with styrene-related substrates.

Diazo reactions with unsaturated compounds: V.1 reaction of phenyl vinyl ether with arenediazonium chlorides

Phenyl vinyl ether reacts with arenediazonium chlorides in aqueous acetone at pH 3-4 in the presence of a catalytic amount of copper(II) chloride to give arylacetaldehydes and small amounts 1-aryl-2-phenoxyethenes. No reaction occurs between the same reactants in the presence of sulfur(IV) oxide. 2000 MAIK "Nauka/Interperiodica".

Diazo Reactions with Unsaturated Compounds. IV. Reaction of Vinyl Butyl Ether with Aryldiazonium Chlorides

Vinyl butyl ether reacts in aqueous acetone at pH 4-5 in the presence of catalytic amounts of copper(II) chloride with aryldiazonium chlorides to give 1-butoxy-2-arylethenes and minor amounts of 1-butoxy-1-chloro-2-arylethanes, which are readily hydrolyzed in an acid medium in the presence of 2,4-dinitrophenylhydrazine to give 2,4-dinitrophenylhydrazones of corresponding arylacetaldehydes.

1-(Carbazol-9-ylmethyl)benzotriazole Anion: A Formyl Anion Equivalent

The title anion, readily available as its lithium derivative, smoothly reacts with a wide range of electrophiles to give well-characterized products which are easily hydrolyzed to the corresponding aldehydes in high overall yields.The method is compared with currently available routes.
