Electrochemical methoxylation of styrene with gas-lift in continuous mode

Anodic oxidation of styrene in methanol was performed in an electrolyzer with gas-lift. The possibility of carrying this process out in continuous mode with the use of technical-grade methanol was studied.

Electrochemical methoxylation of cinnamic acid and its derivatives

Electrochemical methoxylation of cinnamic acid is accompanied by decarboxylation and yields 1,1,2-trimethoxy-2-phenylethane through formation of γ-truxillic acid in the initial stage. Under the same conditions methyl cinnamate and cinnamamide give rise to

The effect of electrolysis conditions on the oxidation of styrene in methanol

Anodic oxidation of styrene (1) in methanol and the effect of the anion of the supporting electrolyte and of the anode material on this process have been studied.The most efficient conversion of 1 into (1,2-dimethoxyethyl)benzene (2) occurs when the electrolysis is carried out with a platinum anode and with potassium fluoride or tetrabutylammonium tetrafluoroborate as the supporting electrolyte.Cleavage of the C-C ? bond in 2 to give benzaldehyde dimethylacetal (3) is the most efficient at a graphite anode in the presence of sodium tosylate. - Key words: styrene, anodic oxidation, electrochemical cleavage of carbon-carbon ? and ? bonds; (1,2-dimethoxyethyl)benzene; benzaldehyde dimethylacetal; (1,1,2-trimethoxyethyl)- and (1,2,2-trimethoxyethyl)benzenes.

SELENIUM CATALYZED CONVERSION OF VINYL HALIDES INTO α-ALKOXY ACETALS

The reaction of vinyl halides with phenylselenenyl chloride in alcohols affords α-alkoxy acetals and diphenyl diselenide which can be oxidized to PhSe cations by nitrate or persulfate anions.The reaction can be carried out with catalytic amounts of PhSeCl or PhSeSePh.The reaction proceeds through the formation of the methoxyselenenylation product which then suffers solvolysis.Under controlled conditions, the 1-phenyl-1-methoxy-2-bromo-2-phenylselenenyl ethane was isolated from the reaction of β-bromostyrene and PhSeCl in methanol.Several deselenenylation reactions of this α-halogenoselenide are reported.
