83791-43-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 83791-43-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,7,9 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 83791-43:
(7*8)+(6*3)+(5*7)+(4*9)+(3*1)+(2*4)+(1*3)=159
159 % 10 = 9
So 83791-43-9 is a valid CAS Registry Number.

Visible-Light-Mediated Liberation and In Situ Conversion of Fluorophosgene

Petzold, Daniel,Nitschke, Philipp,Brandl, Fabian,Scheidler, Veronica,Dick, Bernhard,Gschwind, Ruth M.,K?nig, Burkhard

, p. 361 - 366 (2019)

The first example for the photocatalytic generation of a highly electrophilic intermediate that is not based on radical reactivity is reported. The single-electron reduction of bench-stable and commercially available 4-(trifluoromethoxy)benzonitrile by an organic photosensitizer leads to its fragmentation into fluorophosgene and benzonitrile. The in situ generated fluorophosgene was used for the preparation of carbonates, carbamates, and urea derivatives in moderate to excellent yields via an intramolecular cyclization reaction. Transient spectroscopic investigations suggest the formation of a catalyst charge-transfer complex-dimer as the catalytic active species. Fluorophosgene as a highly reactive intermediate, was indirectly detected via its next downstream carbonyl fluoride intermediate by NMR. Furthermore, detailed NMR analyses provided a comprehensive reaction mechanism including a water dependent off-cycle equilibrium.

Paragraph 0415-0421, (2021/05/26)

The invention relates to a crystal form containing triple-fused-ring derivative free alkali and a pharmaceutical composition thereof. The invention specifically relates to a crystal form of a compound free alkali with a general formula (I), a preparation method, a pharmaceutical composition containing a therapeutically effective amount of the crystal form, and an application of the crystal form in preparation of drugs for treating PI3K-mediated related diseases.

Pd-catalyzed carboamination of oxazolidin-2-ones: A stereoselective route to trans -2,5-disubstituted pyrrolidines

Lemen, Georgia S.,Wolfe, John P.

supporting information; experimental part, p. 2322 - 2325 (2010/07/14)

Palladium-catalyzed carboamination reactions between aryl bromides and 4-(but-3-enyl)-substituted oxazolidin-2-ones are described. These transformations afford bicyclic oxazolidin-2-one derivatives that can be converted to trans-2,5-disubstituted pyrrolid
