70777-66-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 70777-66-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,7,7 and 7 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 70777-66:
(7*7)+(6*0)+(5*7)+(4*7)+(3*7)+(2*6)+(1*6)=151
151 % 10 = 1
So 70777-66-1 is a valid CAS Registry Number.

Nickel-Catalyzed Cyanation of Aryl Halides and Hydrocyanation of Alkynes via C-CN Bond Cleavage and Cyano Transfer

Chen, Hui,Sun, Shuhao,Liu, Yahu A.,Liao, Xuebin

, p. 1397 - 1405 (2020/02/04)

We report nickel-catalyzed cyanation and hydrocyanation methods to prepare aryl nitriles and vinyl nitriles from aryl halides and alkynes, respectively. Using inexpensive and nontoxic 4-cyanopyridine N-oxide as the cyano shuttle, the methods provide an efficient approach to prepare aryl cyanides and vinyl nitriles under mild and operationally simple reaction conditions with a broad range of functional group tolerances. In hydrocyanation of alkynes, the method demonstrated good regioselectivity, producing predominantly E- or Z-alkenyl nitriles in a controlled manner and exclusively Markovnikov vinyl nitriles when internal diaryl alkynes and terminal alkynes were applied as the substrates, respectively. The preliminary mechanistic investigation indicated that the C-CN bond cleavage process is promoted by oxidative addition to the nickel(I) complex in the cyanation of aryl halides, and further studies via a series of deuterium exchange experiments indicated that water serves as the hydrogen source for the hydrocyanation of alkynes.

Stereoarrayed 2,3-Disubstituted 1-Indanols via Ruthenium(II)-Catalyzed Dynamic Kinetic Resolution-Asymmetric Transfer Hydrogenation

Cotman, Andrej Emanuel,Modec, Barbara,Mohar, Barbara

supporting information, p. 2921 - 2924 (2018/05/28)

Activated racemic 2,3-disubstituted 1-indanones 1 possessing two stereolabile centers were stereoselectively reduced to the corresponding chiral 2,3-disubstituted-1-indanols 2 by ruthenium(II)-catalyzed dynamic kinetic resolution-asymmetric transfer hydro

Synthesis, characterisation and photophysical properties of a,a-diaryl-acrylonitrile derivatives

Yue, Youfeng,Fang, Haiyan,Wang, Meijun,Wang, Zhiyuan,Yu, Mingxin

experimental part, p. 377 - 380 (2009/12/25)

a,b-Diarylacrylonitrile derivatives can be prepared by two different routes: (1) the intermolecular condensation of the same arylacetonitriles (2) the condensation of arylaldehydes and arylacetonitriles with a catalytic amount of NaOCH3 at room temperature. Several a,b-diarylacrylonitrile derivatives have been synthesised in this paper and characterised. The UV-vis absorption and photoluminescent (PL) spectra of the products were investigated.
