783-79-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 783-79-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,8 and 3 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 783-79:
(5*7)+(4*8)+(3*3)+(2*7)+(1*9)=99
99 % 10 = 9
So 783-79-9 is a valid CAS Registry Number.

Efficient copper-catalyzed trifluoromethylation of aromatic and heteroaromatic iodides: The beneficial anchoring effect of borates

Gonda, Zsombor,Kovacs, Szabolcs,Weber, Csaba,Gati, Tamas,Meszaros, Attila,Kotschy, Andras,Novak, Zoltan

supporting information, p. 4268 - 4271 (2014/09/30)

Efficient copper-catalyzed trifluoromethylation of aromatic iodides was achieved with TMSCF3 in the presence of trimethylborate. The Lewis acid was used to anchor the in situ generated trifluoromethyl anion and suppress its rapid decomposition. Broad applicability of the new trifluoromethylating reaction was demonstrated in the functionalization of different aromatic and heteroaromatic iodides.

Organocatalysis approach to trifluoromethylation with fluoroform

Zhang, Yuan,Fujiu, Motohiro,Serizawa, Hiroki,Mikami, Koichi

supporting information, p. 367 - 371 (2014/01/06)

The organic base methodology exploits an access to generate the "trifluoromethyl anion" for carbonyl, ester, acid halide, epoxide, deuterium donor, and carbon dioxide substrates to afford the trifluoromethylation products with good overall efficiency even in organocatalysis conditions. The NMR analysis of the mixture of fluoroform and P4-base shows no change thereof. However, on addition of electrophiles, the trifluoromethylation products were obtained efficiently.
