In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Microwave-assisted catalytic upgrading of bio-based furfuryl alcohol to alkyl levulinate over commercial non-metal activated carbon, published in 2020-01-31, which mentions a compound: 591-12-8, Name is 5-Methylfuran-2(3H)-one, Molecular C5H6O2, Computed Properties of C5H6O2.
A cheap and com. available non-metal activated carbon (AC) as an efficient catalyst for the alcoholysis of furfuryl alc. (FA) to alkyl levulinate (AL) under microwave assistance was firstly investigated. The catalyst gave an impressive Me levulinate (ML) yield of 78% in only 5 min at 170 °C in the presence of FA (0.2 M, 3 mL) and AC (100 mg). Various reaction parameters in dependence of time such as temperature, catalyst and feedstock loadings as well as solvent types have been optimized. The re-utilization experiments of the catalyst showed that the activity related to the acidic groups of the catalysts, and the deactivation was due to the leaching of acidic specie, which was easily extracted by the solvent. Note that extremely low concentration of the active species extracted from AC (less than 1 wt %) could also give 62% ML yield. The present study provided a promising way for AL synthesis over cheap, com. available and environmentally benign catalyst.
As far as I know, this compound(591-12-8)Computed Properties of C5H6O2 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
