34645-31-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 34645-31-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,6,4 and 5 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 34645-31:
(7*3)+(6*4)+(5*6)+(4*4)+(3*5)+(2*3)+(1*1)=113
113 % 10 = 3
So 34645-31-3 is a valid CAS Registry Number.

Polymer-bound palladium-catalyzed coupling of allylic alcohols with hypervalent iodonium salts

Jang, Su-Bum

, p. 4421 - 4424 (1997)

The polymer-bound palladium catalyzed cross-coupling reaction of allylic alcohols with hypervalent iodonium sails to form carbon-carbon bonds was achieved at room temperature under extremely mild and aqueous conditions even in the absence of base with very high activity in the Stille coupling reaction. The polymeric catalyst can be easily separated from a reaction mixture and reused more than 10 times with no decrease in activity.

Palladium-catalyzed dienylations of chelated enolates

Basak, Sankar,Kazmaier, Uli

supporting information; experimental part, p. 4169 - 4177 (2009/05/30)

Isomerization-free reactions of dienyl carbonates with chelated amino acid ester enolates at -78 °C provide important information concerning the mechanism of these dienylations. The formation of regioisomeric products can be explained by competing SN2/SN2′ reactions, and the product distribution can be influenced by the proper choice of the reaction conditions. Chiral allylic substrates show a significant transfer of chirality. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.
