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
1-(Ethoxycarbonyl)ethyl Cinnoline-4-carboxylate (32) A solution of 0.75 ml of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) in 20 ml of benzene was added to a stirred suspension of 0.87 g of 1 in 30 ml of benzene at room temperature. After one hour of stirring, 1.36 g of ethyl 2-bromopropionate was added and the mixture was heated at reflux for 6 hours. The mixture was cooled, diluted with 25 ml of benzene, washed with water, 1 N aqueous sodium bicarbonate, and brine. It then was dried (MgSO4), the solvent was evaporated and the residue was chromatographed on silica gel, using a 1:1 v:v mixture of cyclohexane and ethyl acetate as eluent, to give 32, 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
