Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 50-69-1, Name is (2R,3R,4R)-2,3,4,5-Tetrahydroxypentanal, SMILES is O=C[C@@H]([C@@H]([C@@H](CO)O)O)O, belongs to benzodioxans compound. In a document, author is Mironov, Vladimir F., introduce the new discover, Quality Control of (2R,3R,4R)-2,3,4,5-Tetrahydroxypentanal.
The reaction of 4-(1,3,2-benzodioxaphosphol-2-yloxy)-3-tert-butylpent-4-en-2-one with hexafluoroacetone
Catalytic (ZnCl2, Et3N) phosphorylation of tert-butylacetyl-acetone with 2-chloro-1,3,2-benzodioxaphosphole unexpectedly occurs with elimination of proton from the methyl group and leads to vinyloxyphosphole derivative, viz., 4-(1,3,2-benzodioxa-phosphol-2-yloxy)-3-tert-butylpent-4-en-2-one. Its reaction with hexafluoroacetone gives a cage phosphorane as a result of subsequent chemoselective[4+2]- and [3 + 2]-cyclo-additions with stereoselectivity above 95%.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 50-69-1 is helpful to your research. Quality Control of (2R,3R,4R)-2,3,4,5-Tetrahydroxypentanal.
