In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Computed Properties of C8H5N3O2, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 18514-76-6, name is 5-Nitroquinoxaline. In an article，Which mentioned a new discovery about 18514-76-6
Rhodium(III)-catalyzed C-H amidation of 2-arylindoles with dioxazolones for the synthesis of indolo[1,2-c]quinazolines is reported. The reaction is compatible with a wide range of electronically diverse 2-arylindoles and dioxazolones, providing indolo[1,2-c]quinazolines in high to excellent yields. Most notably, the combination of this Rh-catalyzed C-H amidation and intramolecular N-H/N-C(O) cyclization enables the most straightforward direct route to indolo[1,2-c]quinazolines to date. Mechanistic studies and evaluation of antitumor activity of these high value heterocycles are disclosed.
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 18514-76-6, help many people in the next few years.Computed Properties of C8H5N3O2
