In heterogeneous catalysis, the catalyst is in a different phase from the reactants. 21905-86-2, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 21905-86-2, name is C9H6N2O2. In an article£¬Which mentioned a new discovery about 21905-86-2
EXAMPLE 5 n-Propyl Cinnoline-4-carboxylate (5) A suspension of 870 mg of 1, and 850 mg of carbonyidimidazole (CDII) in 30 ml of tetrahydrofuran (THF) was stirred at room temperature until CO2 evolution ceased (ca. 30 minutes). After being stirred for 2 hours, the resulting mixture was treated with 320 mg of dry nypropanol and 3 drops of a 0.1 M solution of sodium imidazole in THE. The mixture was held at room temperature overnight, then the solvent was evaporated and the residue was partitioned between water and ether. The etheral extract was washed with saturated sodium bicarbonate solution, then with brine, then dried (MgSO4) and stripped in a rotary evaporator. The residue was chromatographed over silica gel, using a 1:1 v:v mixture of cyclohexane and ethyl acetate as eluent, to give 5, as a yellow oil.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 21905-86-2., 21905-86-2
