It was established that, in contrast to literature data, even the less stable iron-reagent can be stored for weeks without substantial loss of activity. For complete oxidation of aromatic alcohols to carbonyl compounds there is no need for a significant excess of the reagents proposed in the literature. With an amount of iron-reagent less than the equivalent to the alcohol, the oxidation yield achieved was higher than proportional. This fact may place in doubt the adequacy of the accepted reaction mechanism. The rate of oxidation is markedly influenced by the nature of the solvent, the reaction is the fastest in benzene. The copper-reagent, which has not been used for this purpose before, is a good oxidant too. However, the oxidation yield with this reagent reaches that obtained with the iron reagent at a temperature by about 30-degrees-C higher. In the nitration of phenols the temperature could be increased to 60-degrees-C with the iron-reagent, so we have succeeded in reducing the reaction time to some hours.}, year = {1991}, pages = {339-343} } @article{MTMT:1002138, title = {Oscillatory kinetics of the permanganate oxidation of oxalic acid?}, url = {https://m2.mtmt.hu/api/publication/1002138}, author = {Kéki, Sándor and Beck, Mihály}, doi = {10.1007/BF02068387}, journal-iso = {REACT KINET CATAL L}, journal = {REACTION KINETICS AND CATALYSIS LETTERS}, volume = {44}, unique-id = {1002138}, issn = {0133-1736}, year = {1991}, eissn = {1588-2837}, pages = {75-77} } @article{MTMT:1049593, title = {TEMPERATURE-DEPENDENCE OF THE ENANTIOSELECTIVE HYDROFORMYLATION WITH PTCL2[(S)-BINAP] + SNCL2 CATALYST AND THE DYNAMIC NMR-STUDY OF THE CATALYTIC PRECURSOR}, url = {https://m2.mtmt.hu/api/publication/1049593}, author = {Kollár, László and Sandor, P and Szalontai, Gábor}, doi = {10.1016/0304-5102(91)85046-5}, journal-iso = {J MOL CATAL}, journal = {JOURNAL OF MOLECULAR CATALYSIS}, volume = {67}, unique-id = {1049593}, issn = {0304-5102}, year = {1991}, pages = {191-198}, orcid-numbers = {Szalontai, Gábor/0000-0002-3065-9012} } @article{MTMT:1092482, title = {Kinetics of the Ring-opening Carbonylation of Ethyloxirane with Hydrido Tetracarbonyl Cobalt}, url = {https://m2.mtmt.hu/api/publication/1092482}, author = {Kreisz, J and Ungvary, F and Sisak, Attila and Markó, László}, doi = {10.1016/0022-328X(91)80163-E}, journal-iso = {J ORGANOMET CHEM}, journal = {JOURNAL OF ORGANOMETALLIC CHEMISTRY}, volume = {417}, unique-id = {1092482}, issn = {0022-328X}, abstract = {The rate of CO uptake in the reaction of HCo(CO)4 with ethyloxirane, which gives (3-hydroxypentanoyl)cobalt tetracarbonyl as the major product in an n-octane/methyl isobutyl ketone solvent mixture at 15-degrees-C, is first order with respect to HCo(CO)4 and ethyloxirane, and independent of the concentration of Co(CO)4- or CO.
