40366-99-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40366-99-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,3,6 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 40366-99:
(7*4)+(6*0)+(5*3)+(4*6)+(3*6)+(2*9)+(1*9)=112
112 % 10 = 2
So 40366-99-2 is a valid CAS Registry Number.

Copper-catalyzed intramolecular dehydrogenative aminooxygenation: Direct access to formyl-substituted aromatic N-heterocycles

Wang, Honggen,Wang, Yong,Liang, Dongdong,Liu, Lanying,Zhang, Jiancun,Zhu, Qiang

, p. 5678 - 5681 (2011)

A direct synthesis of carbaldehydes through intramolecular dehydrogenative aminooxygenation has been developed. The process uses a catalytic amount of copper(II) in DMF or DMA under oxygen and does not require additional oxidants (see scheme). Mechanistic studies suggest that the carbonyl oxygen atom of the aldehyde is derived from oxygen through a copper-mediated oxygen activation process via a peroxy-copper(III) intermediate. Copyright

Cu(II)-mediated aminooxygenation of alkenylimines and alkenylamidines with TEMPO

Sanjaya, Stephen,Chua, Sze Hui,Chiba, Shunsuke

supporting information; experimental part, p. 1657 - 1661 (2012/07/17)

A method for the synthesis of oxymethyl dihydropyrroles (pyrrolines) and dihydroimidazoles has been developed via Cu(II)-mediated intramolecular aminooxygenation of alkenylimines and alkenylamidines, respectively, with 2,2,6,6-tetramethyl-1-piperidinyloxy radical (TEMPO).
