In heterogeneous catalysis, the catalyst is in a different phase from the reactants. name: 3-Hydroxyisobenzofuran-1(3H)-one, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 16859-59-9, name is 3-Hydroxyisobenzofuran-1(3H)-one. In an article£¬Which mentioned a new discovery about 16859-59-9
First measurements of absolute rate constants for oxacarbene intermediates produced in the photochemistry of benzocyclobutenedione
The photochemistry of benzocyclobutenedione in solution has been examined by use of laser flash photolysis techniques. Two rapid processes appear to compete. One leads to the formation of the long-lived bisketene IV, which can be readily observed (lambdamax 380 nm). The other process leads to oxacarbene III. This carbene could not be monitored directly, but probing techniques, with pyridine and adamantanethione as probes, lead to readily detectable ylides that can be employed to characterize the kinetic behavior of III. Thus, III lives about 20 mus in toluene and can be trapped by typical carbene scavengers such as alcohols. Carbene trapping by alcohols is in fact a complex reaction, since it also leads to equilibration with a short-lived intermediate (studied in detail in methanol/acetonitrile) that in turn can be trapped by alcohols, azides, and halides. This intermediate is tentatively assigned to carbocation VIII formed by solvent protonation of III.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 16859-59-9, help many people in the next few years.name: 3-Hydroxyisobenzofuran-1(3H)-one
