In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Formula: C4H4O3, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 4971-56-6, name is Furan-2,4(3H,5H)-dione. In an article，Which mentioned a new discovery about 4971-56-6
3,3,3-Trifluoro-1-nitropropene as a Novel Trifluoromethyl-Containing Building Block
Additions of various carbanion nucleophiles to 3,3,3-trifluoro-1-nitropropene (1) proceeded regiospecifically at the C-2 position of 1 to give the corresponding adducts.The nitro group of the adducts, derived from the reactions with acetylacetone and ethyl acetoacetate, was reduced to the corresponding amines, which were cyclized in situ to the 3-(trifluoromethyl)pyrrole derivatives.
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 4971-56-6, help many people in the next few years.Formula: C4H4O3
