69905-97-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 69905-97-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,9,0 and 5 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 69905-97:
(7*6)+(6*9)+(5*9)+(4*0)+(3*5)+(2*9)+(1*7)=181
181 % 10 = 1
So 69905-97-1 is a valid CAS Registry Number.

Iron-catalysed sequential reaction towards α-aminonitriles from secondary amines, primary alcohols and trimethylsilyl cyanide

Shen, Hang,Hu, Liangzhen,Liu, Qing,Hussain, Muhammad Ijaz,Pan, Jing,Huang, Mingming,Xiong, Yan

, p. 2776 - 2779 (2016)

We have developed a one-pot iron-catalysed sequential reaction of secondary amines with primary alcohols, trimethylsilyl cyanide and TBHP under mild reaction conditions to give the corresponding α-aminonitriles.

Covalently hooked EOSIN-Y in a Zr(IV) framework as visible-light mediated, heterogeneous photocatalyst for efficient C–H functionalization of tertiary amines

Kumar, Gaurav,Solanki, Pratik,Nazish, Mohd,Neogi, Subhadip,Kureshy, Rukhsana I.,Khan, Noor-ul H.

, p. 298 - 304 (2019/02/26)

Herein, we report the synthesis of a novel heterogeneous photo-catalyst by utilizing post-synthetic modification of an amine functionalized Zr(IV) metal-organic framework (UiO-66-NH2) through covalent hooking of EOSIN-Y via dehydrating coupling. The characterization of the catalyst was accomplished by FT-IR, XRD, BET surface analysis, TGA, as well as TEM, SEM, XPS, DRS-UV–visible, and NMR spectroscopy, confirming successful covalent linking of EOSIN-Y with the pendent –NH2 functionality in the framework. That post-modified EY@UiO-66-NH2 acts as simple and green visible light mediated photo-catalyst for the C–H activation of tertiary amines with excellent yields. Importantly, the activity of dye incorporated heterogeneous photo-catalyst is found superior to that for the homogeneous photo-catalyst EOSIN-Y. Thus, separation difficulty of homogeneous catalysis, as well as the environmental adverse effects of toxic EOSIN-Y can be excluded by developing such photo-catalyst. Moreover, EY@UiO-66-NH2 catalyst could be consistently recycled up to 10 cycles, without any significant loss in activity. Based on literature report and experimental findings, we also propose a plausible mechanism for the reaction.

Ruthenium-catalyzed oxidative cyanation of tertiary amines with hydrogen peroxide and sodium cyanide

Murahashi, Shun-Ichi,Komiya, Naruyoshi,Terai, Hiroyuki

, p. 6931 - 6933 (2007/10/03)

(Chemical Equation Presented) Versatile intermediates for the synthesis of N-aryl-α-amino acids and N,N-disubstituted 1,2-diamines can now be synthesized with high efficiency by the ruthenium-catalyzed oxidative cyanation of tertiary amines. The use of hy
