17271-70-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 17271-70-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,2,7 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 17271-70:
(7*1)+(6*7)+(5*2)+(4*7)+(3*1)+(2*7)+(1*0)=104
104 % 10 = 4
So 17271-70-4 is a valid CAS Registry Number.

Enantioselective Resolution Copolymerization of Racemic 2,3-Disubstituted cis-Epoxides with CO2 Mediated by Binuclear Cobalt(III) Catalyst?

He, Guang-Hui,Liu, Yan-Lan,Liu, Ye,Lu, Xiao-Bing

, p. 2386 - 2390 (2021/07/12)

Enantioselective resolution copolymerization of racemic internal epoxides with carbon dioxide (CO2) is a challenging issue because of their poor reactivity and complicated regio/stereoselectivity. Herein, we describe the first enantioselective

Visible photocatalysis of novel oxime phosphonates: Synthesis of β-aminophosphonates

Li, Yong-Hong,Wang, Chun-Hai,Gao, Su-Qian,Qi, Feng-Ming,Yang, Shang-Dong

supporting information, p. 11888 - 11891 (2019/10/11)

A novel type of oxime phosphonate was synthesized and used in the intermolecular cascade radical addition reaction of alkenes to access β-aminophosphonates via visible-light-driven N-centered iminyl radical-mediated and redox-neutral selective C-P single-bond cleavage in an active phosphorus radical route. The procedure is characterized by its ability to achieve the construction of Csp3-P and Csp3-N bonds without the requirement for oxidants and bases.

Amide and amine nucleophiles in polar radical crossover cycloadditions: Synthesis of γ-lactams and pyrrolidines

Gesmundo, Nathan J.,Grandjean, Jean-Marc M.,Nicewicz, David A.

supporting information, p. 1316 - 1319 (2015/03/14)

In this work we present a direct catalytic synthesis of γ-lactams and pyrrolidines from alkenes and activated unsaturated amides or protected unsaturated amines, respectively. Using a mesityl acridinium single electron photooxidant and a thiophenol cocata

Gas-Phase Reactions of Charged Electrophiles with Styrene and Phenylacetylene

Crestoni, Maria Elisa,Fornarini, Simonetta

, p. 6008 - 6014 (2007/10/02)

The reactions of styrene and phenylacetylene toward charged electrophiles have been studied in the gas phase by a radiolytic technique, supported by chemical ionization mass spectrometry.The two substrates undergo a methylation reaction by Me2F(1+) both at the ring and at the side chain, at variance with the side-chain electrophilic attack prevailing in condensed phase.The nitrating (MeONO2)H(1+) ion selectively nitrates the orto position of styrene, an unprecedented ring nitration on this substrate.The formation of neutral isomeric products is determined by the efficiency of deprotonation of their ionic precursors and is sensitive interalia to the presence of oxygen nucleophiles.The overall reactivity pattern is rationalized in terms of preferential electrostatic interactions between the reactants in a preliminary collision complex, whereby an incoming ROH molecule can simulate a "solvating" environment, shifting the reactivity in the direction observed in solution.
