2765-16-4 Usage

General Description

"Benzene, 1,1'-(1,2-ethynediyl)bis[3-methyl-" is a complex organic chemical compound that belongs to the family of aromatic hydrocarbons. It is commonly used in the manufacturing of a variety of chemical products. The compound contains two benzene rings, each substituted with a methyl group, and is linked together by an ethynediyl bridge. Like other benzene derivatives, it should be handled with caution as prolonged exposure can potentially lead to health issues. While it plays a significant role in various chemical reactions and industrial applications, its production and use should be managed carefully due to its potential environmental impact.

Check Digit Verification of cas no

The CAS Registry Mumber 2765-16-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,6 and 5 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2765-16:
(6*2)+(5*7)+(4*6)+(3*5)+(2*1)+(1*6)=94
94 % 10 = 4
So 2765-16-4 is a valid CAS Registry Number.

Synthesis of Diarylethynes from Aryldiazonium Salts by Using Calcium Carbide as an Alkyne Source in a Deep Eutectic Solvent

Ma, Xiaolong,Li, Zheng

supporting information, p. 631 - 635 (2020/12/28)

An efficient method for the synthesis of diarylethynes from aryldiazonium salts by using calcium carbide as an alkyne source at room temperature in a deep eutectic solvent is described. The salient features of this protocol are an inexpensive and easy-to-handle alkyne source, a nonvolatile and recyclable solvent, mild conditions, and a simple workup procedure.

Rhodium-Catalyzed Regioselective Hydroformylation of Alkynes to α,β-Unsaturated Aldehydes Using Formic Acid

Fan, Chao,Hou, Jing,Chen, Yu-Jia,Ding, Kui-Ling,Zhou, Qi-Lin

supporting information, p. 2074 - 2077 (2021/04/05)

A rhodium-catalyzed hydroformylation of alkynes with formic acid was developed. The method provides α,β-unsaturated aldehydes in high yield and E-selectivity without the need to handle toxic CO gas.

Rh(iii)-Catalyzed three-component cascade annulation to produce theN-oxopropyl chain of isoquinolone derivatives

He, Yuan,Liao, Xian-Zhang,Dong, Lin,Chen, Fen-Er

supporting information, p. 561 - 567 (2021/02/06)

Developing powerful methods to introduce versatile functional groups at theN-substituents of isoquinolone scaffolds is still a great challenge. Herein, we report a novel three-component cascade annulation reaction to efficiently construct theN-oxopropyl chain of isoquinolone derivativesviarhodium(iii)-catalyzed C-H activation/cyclization/nucleophilic attack, with oxazoles used both as the directing group and potential functionalized reagents.
