THE STAGE CHARACTER OF THE OXIDATION OF DIALKYLTHIOPHENES

The reasons for the stage character of the oxidation of dialkylthiophenes catalyzed by a cobalt bromide catalyst are examined.The stage character of oxidation is due to the deactivation of the catalyst by the corresponding alcohol formed during oxidation.At the first stage of the process only the product from oxidation of the α-alkyl group, i.e., the corresponding ketone, ester, and thiophenecarboxylc acid, are formed.The rate constants for their formation were calculated.
CATALYTIC ACTIVITY OF THE CARBOXYLATE COMPLEXES OF COBALT(II) WITH NITROGEN-CONTAINING HETEROCYCLIC LIGANDS IN THE LIQUID-PHASE OXIDATION OF DIALKYLTHIOPHENES

The dimeric carboxylate complexes of cobalt(II) with pyridine, quinoline, and quinaldine exhibit fairly high catalytic activity in the liquid-phase oxidation of dialkylthiophenes.The monomeric complex with 2,2'-bipyridyl does not exhibit catalytic activity.
