PROCESS FOR THE PREPARATION OF 1,4-SUBSTITUTED 2-BUTENE-1,4-DIONES

PROCESS FOR THE PREPARATION OF 1,4-SUBSTITUTED 2-BUTENE-1,4-DIONES

But-2-ene-1,4-diones substituted in the 1,4-positions, of the formula I where R1 and R2 are each an aliphatic hydrocarbon radical of 1 to 17 carbon atoms, are prepared by a process in which a 2,5-disubstituted furan of the formula II where R1 and R2 have the above meaning, is oxidized with a percarb...

Zusammenfassung:But-2-ene-1,4-diones substituted in the 1,4-positions, of the formula I where R1 and R2 are each an aliphatic hydrocarbon radical of 1 to 17 carbon atoms, are prepared by a process in which a 2,5-disubstituted furan of the formula II where R1 and R2 have the above meaning, is oxidized with a percarboxylic acid in the presence of a carboxylic acid.
