58686-68-3 Usage

General Description

"(3-Chloro-phenyl)-propynoic acid ethyl ester is a chemical compound with the molecular formula C10H9ClO2. It is a derivative of propynoic acid, with an ethyl ester group attached. (3-CHLORO-PHENYL)-PROPYNOIC ACID ETHYL ESTER is a yellowish liquid at room temperature and is primarily used as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It is also known to have some biological activity, although its specific properties and applications are still being studied. The presence of the chloro-phenyl group in this compound makes it a valuable building block for the synthesis of various organic compounds in the pharmaceutical and agricultural industries."

Check Digit Verification of cas no

The CAS Registry Mumber 58686-68-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,6,8 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 58686-68:
(7*5)+(6*8)+(5*6)+(4*8)+(3*6)+(2*6)+(1*8)=183
183 % 10 = 3
So 58686-68-3 is a valid CAS Registry Number.

De Novo Construction of Substituted Terephthalates via Phosphine Catalyzed Domino Benzannulation Reactions

Wang, Dan,Lin, Junhui,Zhu, Yannan,Huang, You

supporting information, p. 1873 - 1877 (2021/02/16)

The robustness of phosphine catalysis enabling the domino benzannulation reactions of allenoates with enamines is described. A broad array of substituted terephthalates were delivered under simple and practical reaction conditions. Furthermore, the reaction could be carried out on a gram scale with higher yield, and various conversions of the terephthalate products demonstrate the versatility of this transformation. (Figure presented.).

3-Phenothiazinyl propiolates – Fluorescent electrophores by Sonogashira coupling of ethyl propiolate

G?tzinger, Alissa C.,Michaelis, Carina S.,Müller, Thomas J.J.

, p. 308 - 316 (2017/05/04)

Fluorescent ethyl 3-phenothiazinyl propiolates with reversible Nernstian oxidation potentials were efficiently synthesized by an improved Sonogashira coupling of aryl iodides and ethyl propiolate. The versatility of this modified alkynylation was illustrated by 13 ethyl 3-arylpropiolates in mostly excellent yields with a broad substrate scope. In addition to reversible one-electron oxidations, the title compounds reveal large Stokes shifts, high fluorescence quantum yields, and solvatochromic emission. The photophysical characteristics were corroborated and rationalized by DFT and TD-DFT calculations.

Copper(i)/phosphine-catalyzed tandem carboxylation/annulation of terminal alkynes under ambient pressure of CO2: One-pot access to 3a-hydroxyisoxazolo[3,2-a]isoindol-8(3aH)-ones

Xie, Jia-Ning,Yu, Bing,Guo, Chun-Xiang,He, Liang-Nian

, p. 4061 - 4067 (2015/07/15)

An efficient method for the synthesis of 3a-hydroxyisoxazolo[3,2-a]isoindol-8(3aH)-ones from CO2, terminal alkynes, EtBr, and NHPI (N-hydroxyphthalimide) was developed through a tandem carboxylation/annulation strategy catalyzed by a copper(i)/phosphine system. This one-pot multicomponent reaction was conducted at atmospheric CO2 pressure to afford the target products in good to excellent yields under mild conditions. Notably, a wide range of functional groups were tolerated in this procedure. This protocol with simultaneous formation of four novel bonds i.e. two C-C bonds and two C-O bonds represents an efficient methodology for upgrading CO2 into heterocycles.
