69520-13-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 69520-13-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,5,2 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 69520-13:
134 % 10 = 4
So 69520-13-4 is a valid CAS Registry Number.

Photoredox-Catalyzed Hydrosulfonylation of Arylallenes

Detistova, Galina I.,Festa, Alexey A.,Rybakov, Victor B.,Storozhenko, Olga A.,Van Der Eycken, Erik V.,Varlamov, Alexey V.,Voskressensky, Leonid G.

, (2020)

(Het)Arylallenes undergo hydrosulfonylation under photoredox-catalyzed conditions. The reaction gives vinyl sulfones in a regio- and diastereoselective manner, employing sodium sulfinates as the sulfonyl source and eosin Y as the photocatalyst. Indol-1-yl, pyrrol-1-yl, phenyl, and naphtylallenes might be used. Aliphatic allenes are incompatible with the reaction conditions.

Palladium-catalyzed coupling of vinyl tosylates with arylsulfinate salts

Reeves, Diana C.,Rodriguez, Sonia,Lee, Heewon,Haddad, Nizar,Krishnamurthy, Dhileep,Senanayake, Chris H.

experimental part, p. 2870 - 2873 (2009/09/06)

The first palladium-catalyzed coupling of vinyl tosylates with arylsulfinate salts is described. A variety of cyclic and acyclic vinyl tosylates were coupled with aryl sulfinate salts using 2.5 mol % Pd2(dba)3/5.0 mol % XantPhos to g
