24332-24-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 24332-24-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,3,3 and 2 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 24332-24:
(7*2)+(6*4)+(5*3)+(4*3)+(3*2)+(2*2)+(1*4)=79
79 % 10 = 9
So 24332-24-9 is a valid CAS Registry Number.

Domino gold-catalyzed rearrangement and fluorination of propargyl acetates

De Haro, Teresa,Nevado, Cristina

supporting information; experimental part, p. 248 - 249 (2011/02/23)

A combination of IPrAuNTf2 as catalyst in the presence of Selectfluor has been successfully used for the high yielding synthesis of α-fluoroenones via 1,3-acyloxy rearrangement of propargyl acetates followed by Csp2-F bond formation,

Gold-catalyzed efficient preparation of linear α-haloenones from propargylic acetates

Yu, Meng,Zhang, Guozhu,Zhang, Liming

experimental part, p. 1846 - 1855 (2009/07/04)

Versatile linear α-iodo- and α-bromoenones are prepared efficiently from readily accessible propargylic acetates using 2 mol % of Au(PPh3)NTf2. This reaction is easy to execute and has broad substrate scope. Good to excellent Z-selectivities are observed in the cases of propargylic acetates derived from aliphatic aldehydes.

Gold-catalyzed efficient preparation of linear α-lodoenones from propargylic acetates

Yu, Meng,Zhang, Guozhu,Zhang, Liming

, p. 2147 - 2150 (2008/02/03)

Only 2 mol % of Au(PPh3)NTf2 is needed to convert readily accessible propargylic acetates into versatile linear α-iodoenones in good to excellent yields. This reaction is easy to execute and has broad substrate scope. Good to excellent Z-selectivities are observed in the cases of aliphatic propargylic acetates derived from aldehydes.
