16728-56-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 16728-56-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,7,2 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 16728-56:
(7*1)+(6*6)+(5*7)+(4*2)+(3*8)+(2*5)+(1*6)=126
126 % 10 = 6
So 16728-56-6 is a valid CAS Registry Number.

Dehydrogenation of Primary Alkyl Azides to Nitriles Catalyzed by Pincer Iridium/Ruthenium Complexes

Gan, Lan,Jia, Xiangqing,Fang, Huaquan,Liu, Guixia,Huang, Zheng

, p. 3661 - 3665 (2020/06/02)

Pincer metal complexes exhibit superior catalytic activity in the dehydrogenation of plain alkanes, but find limited application in the dehydrogenation of functionalized organic molecules. Starting from easily accessible primary alkyl azides, here we report an efficient dehydrogenation of azides to nitriles using pincer iridium or ruthenium complexes as the catalysts. This method offers a route to cyanide-free preparation of nitriles without carbon chain elongation and without the use of strong oxidants. Both benzyl and linear aliphatic azides can be dehydrogenated with tert-butylethylene as the hydrogen acceptor to afford nitriles in moderate to high yields. Various functional groups can be tolerated, and the H?C?C?H bond dehydrogenation does not occur for linear alkyl azide substrates. Furthermore, the pincer Ir catalytic system was found to catalyze the direct azide dehydrogenation without the use of a sacrificial hydrogen acceptor.

Synthesis of novel mono and bis nitric oxide donors with high cytocompatibility and release activity

supporting information, p. 3329 - 3332 (2018/09/27)

Four compounds bearing amidoxime functions were synthetized: (1) 2a,b bearing an aromatic amidoxime function, (2) 2c bearing an aliphatic amidoxime function, and (3) 2d bearing aromatic and aliphatic amidoximes functions. The ability of these compounds to

Radical cyanation of alkyl iodides with diethylphosphoryl cyanide

Chang, Ho Cho,Jin, Young Lee,Kim, Sunggak

experimental part, p. 81 - 84 (2009/05/30)

The β-elimination of an organophosphoryl group from an iminyl radical is observed for the first time. On the basis of this finding, radical cyanation of alkyl iodides is achieved by using diethylphosphoryl cyanide. Georg Thieme Verlag Stuttgart.
