147219-88-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 147219-88-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,2,1 and 9 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 147219-88:
(8*1)+(7*4)+(6*7)+(5*2)+(4*1)+(3*9)+(2*8)+(1*8)=143
143 % 10 = 3
So 147219-88-3 is a valid CAS Registry Number.

Synthesis of spiroindanes by palladium-catalyzed oxidative annulation of non- or weakly activated 1,3-dienes involving C-H functionalization

Khan, Imtiaz,Chidipudi, Suresh Reddy,Lam, Hon Wai

, p. 2613 - 2616 (2015)

The synthesis of spiroindanes by the palladium-catalyzed oxidative annulation of non- or weakly activated 1,3-dienes with 2-aryl cyclic 1,3-dicarbonyl compounds is described. Examples of the dearomatizing oxidative annulation of 1,3-dienes with 1-aryl-2-naphthols are also presented. This journal is

Rhodium-Catalyzed Oxidative C-H Allylation of Benzamides with 1,3-Dienes by Allyl-to-Allyl 1,4-Rh(III) Migration

Korkis, Stamatis E.,Burns, David J.,Lam, Hon Wai

supporting information, p. 12252 - 12257 (2016/09/28)

The Rh(III)-catalyzed oxidative C-H allylation of N-acetylbenzamides with 1,3-dienes is described. The presence of allylic hydrogens cis to the less substituted alkene of the 1,3-diene is important for the success of these reactions. With the assistance of reactions using deuterated 1,3-dienes, a proposed mechanism is provided. The key step is postulated to be the first reported examples of allyl-to-allyl 1,4-Rh(III) migration.

Lewis acid-promoted addition of 1,3-bis(silyl)propenes to aldehydes: A route to 1,3-dienes

Borg, Tessie,Tuzina, Pavel,Somfai, Peter

experimental part, p. 8070 - 8075 (2011/11/28)

The Lewis acid-promoted addition of 1,3-bis(silyl)-propenes to aldehydes to provide the corresponding (E)-1,3-dienes in excellent stereoselectivity and good to excellent yields is reported. The procedure is mild, base-free, and operationally straightforward.
