70550-40-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 70550-40-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,5,5 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 70550-40:
(7*7)+(6*0)+(5*5)+(4*5)+(3*0)+(2*4)+(1*0)=102
102 % 10 = 2
So 70550-40-2 is a valid CAS Registry Number.

Microwave-Assisted Condensation of Benzylic Alcohols and Alkynes Promoted by Zinc Halides: Concise Access to Alkenyl Halides

Goel, Komal,Nandi, Poulomi,Satyanarayana, Gedu,Sreenivasulu, Chinnabattigalla

supporting information, p. 4851 - 4860 (2021/11/17)

A simple Lewis acid-mediated route for the synthesis of alkenyl halides are described under microwave-assisted conditions. The reaction proceeds through the condensation between secondary alcohols and terminal acetylenes and regioselective hydrohalogenati

Fe powder catalyzed highly efficient synthesis of alkenyl halides via direct coupling of alcohols and alkynes with aqueous HX as exogenous halide sources

Yang, Yong-Rong,Zhang, Qiang,Du, Feng-Tian,Ji, Jian-Xin

supporting information, p. 4304 - 4311 (2015/06/08)

A simple and efficient catalytic method for the synthesis of alkenyl halides via direct coupling of alcohols and alkynes using aqueous HX (X=Cl, Br) as halide sources has been developed under mild conditions in the presence of Fe powder (1 mol %). In comp

FeX3-promoted intermolecular addition of benzylic alcohols to aromatic alkynes: A mild and efficient strategy for the synthesis of alkenyl halides

Ren, Kai,Wang, Min,Wang, Lei

experimental part, p. 565 - 571 (2010/04/28)

A convenient, effective, mild and simple strategy has been developed for the synthesis of alkenyl halides by the intermolecular addition of benzylic alcohols to aromatic alkynes. The reactions were carried out in the presence of iron(III) bromide or chloride in 1, 2-dibromoethane without additives in air at room temperature. Alkenyl bromides and chlorides were obtained with high regio- and stereoselectivity (E/Z up to 99:1) in good-to-excellent yields in 0.5-1 h under mild reaction conditions.

An efficient and mild iron-mediated synthesis of alkenyl halides via direct C-C bond formation of benzyl alcohols and aryl alkynes

Liu, Zhong-Quan,Wang, Jianguo,Han, Jie,Zhao, Yankai,Zhou, Bo

experimental part, p. 1240 - 1242 (2009/05/27)

This work demonstrated an efficient and mild method for preparing various substituted alkenyl halides via direct C-C bond formation of benzyl alcohols and aryl alkynes in CH2Cl2 at 50 °C by using 50 mol % of FeCl3·6H2

New and efficient iron halide mediated synthesis of alkenyl halides through coupling of alkynes and alcohols

Biswas, Srijit,Maiti, Sukhendu,Jana, Umasish

supporting information; experimental part, p. 2354 - 2359 (2009/09/05)

A novel, simple, and straightforward one-pot reaction of alkynes with various alcohols in the presence of iron salts (FeCl3 and FeBr 3) was described to yield the corresponding alkenyl halides with complete regioselectivity and high

Formation of Disubstituted Chloro-olefins by Treatment of Substituted 1,2-Dichloroethylenes with Hydrocarbons in the Vapour Phase

Milner, David J.

, p. 3241 - 3255 (2007/10/02)

Disubstituted chloro-olefins RCH=CR1Cl together with hydrogen chloride have been formed by treatment of substituted 1,2-dichloroethylenes with hydrocarbons in the gas phase in a flow system at 500 to 600 deg C.Some stereoselectivity towards formation of the Z isomers was observed.The results are interpreted in terms of a free-radical chain mechanism.
