Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, causing turnover rates to depend strongly on interfacial structure and composition, 619-65-8, Name is 4-Cyanobenzoic acid, SMILES is O=C(O)C1=CC=C(C#N)C=C1, in an article , author is Mironov, Vladimir F., once mentioned of 619-65-8, Category: benzodioxans.
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%.
