72238-87-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 72238-87-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,2,3 and 8 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 72238-87:
(7*7)+(6*2)+(5*2)+(4*3)+(3*8)+(2*8)+(1*7)=130
130 % 10 = 0
So 72238-87-0 is a valid CAS Registry Number.

Activation of 1,1-difluoro-1-alkenes with a transition-metal complex: Palladium(II)-catalyzed friedel - crafts-type cyclization of 4,4-(difluorohomoallyl)arenes

Yokota, Misaki,Fujita, Daishi,Ichikawa, Junji

, p. 4639 - 4642 (2007)

(Chemical Equation Presented) Cationic palladium(II) ([Pd(MeCN) 4](BF4)2) provides the first transition-metal-catalyzed method for electrophilic activation of electron-deficient 1,1-difluoro-1-alkenes, which allows their Friedel-Crafts-type cyclization with an intramolecular aryl group via a Wacker-type process. By using BF3·OEt2, the cyclization was effected by a catalytic amount of the palladium without its reoxidation.
