82807-53-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 82807-53-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,8,0 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 82807-53:
(7*8)+(6*2)+(5*8)+(4*0)+(3*7)+(2*5)+(1*3)=142
142 % 10 = 2
So 82807-53-2 is a valid CAS Registry Number.

Cu(II)-Catalyzed ortho-Selective Aminomethylation of Phenols

Dai, Jin-Ling,Shao, Nan-Qi,Zhang, Jin,Jia, Run-Ping,Wang, Dong-Hui

supporting information, p. 12390 - 12393 (2017/09/23)

A Cu(II)-catalyzed ortho-selective functionalization of free phenols with trifluoroborates to afford Csp2-Csp3 coupling products under mild conditions has been developed. A variety of functional groups on the phenol and the potassium aminomethyltrifluoroborate substrates were found compatible, furnishing the corresponding products in moderate to excellent yields. A single-electron transfer radical coupling mechanism involving a six-membered transition state is proposed to rationalize the high levels of ortho-selectivity in the reaction. This protocol provides straightforward access to ortho-aminomethyl-substituted phenols, unnatural amino acids and other bioactive small molecules.

Synthesis of N-[2-hydroxy-4(5)-methyl- and -5-(methylcyclohexyl)benzyl] morpholines as antioxidants for transformer oils

Rasulov, Ch. K.,Azizov,Nabiev,Rustamov,Askerova

experimental part, p. 2140 - 2143 (2011/05/07)

Aminomethylation of m- and p-cresols and of p-(1-methylcyclohexyl)phenol with formaldehyde and morpholine was studied. The products obtained were tested as antioxidant additives to T-1500 transformer oil.
