General Description

1-Nitro-4-prop-2-yn-1-ylbenzene, also known as 4-ethynyl-1-nitrobenzene, is a chemical compound with the molecular formula C9H7NO2. It is a yellow crystalline solid commonly used in the synthesis of pharmaceuticals and organic compounds. This chemical is classified as a nitro compound due to the presence of a nitro group (NO2) attached to a benzene ring. It is also characterized by the prop-2-yn-1-yl group, which consists of a carbon chain with a triple bond attached to the benzene ring. 1-Nitro-4-prop-2-yn-1-ylbenzene is primarily used as a building block in organic synthesis and can undergo various chemical reactions to produce a wide range of derivatives with different functional groups. Its potential applications include in the production of dyes, pigments, and chemical intermediates. However, it is important to handle this compound with caution, as it is considered hazardous due to its potential toxicity and flammability.

Check Digit Verification of cas no

The CAS Registry Mumber 13540-76-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,5,4 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 13540-76:
(7*1)+(6*3)+(5*5)+(4*4)+(3*0)+(2*7)+(1*6)=86
86 % 10 = 6
So 13540-76-6 is a valid CAS Registry Number.

Iron-Catalyzed Vinylzincation of Terminal Alkynes

Organozinc reagents are among the most commonly used organometallic reagents in modern synthetic chemistry, and multifunctionalized organozinc reagents can be synthesized from structurally simple, readily available ones by means of alkyne carbozincation. However, this method suffers from poor tolerance for terminal alkynes, and transformation of the newly introduced organic groups is difficult, which limits its applications. Herein, we report a method for vinylzincation of terminal alkynes catalyzed by newly developed iron catalysts bearing 1,10-phenanthroline-imine ligands. This method provides efficient access to novel organozinc reagents with a diverse array of structures and functional groups from readily available vinylzinc reagents and terminal alkynes. The method features excellent functional group tolerance (tolerated functional groups include amino, amide, cyano, ester, hydroxyl, sulfonyl, acetal, phosphono, pyridyl), a good substrate scope (suitable terminal alkynes include aryl, alkenyl, and alkyl acetylenes bearing various functional groups), and high chemoselectivity, regioselectivity, and stereoselectivity. The method could significantly improve the synthetic efficiency of various important bioactive molecules, including vitamin A. Mechanistic studies indicate that the new iron-1,10-phenanthroline-imine catalysts developed in this study have an extremely crowded reaction pocket, which promotes efficient transfer of the vinyl group to the alkynes, disfavors substitution reactions between the zinc reagent and the terminal C–H bond of the alkynes, and prevents the further reactions of the products. Our findings show that iron catalysts can be superior to other metal catalysts in terms of activity, chemoselectivity, regioselectivity, and stereoselectivity when suitable ligands are used.

Ruthenium-Catalyzed Propargylic Reduction of Propargylic Alcohols with Hantzsch Ester

supporting information, p. 2130 - 2134 (2020/06/08)

Ruthenium-catalyzed propargylic reduction of propargylic alcohols bearing a terminal alkyne moiety is accomplished by using Hantzsch ester as a nucleophilic hydride source. A variety of secondary and tertiary propargylic alcohols are reduced to the corresponding propargylic reduced products such as 1-alkynes in excellent yields. Some mechanistic studies indicate that ruthenium-allenylidene complexes may work as key reactive intermediates.
