A highly efficient silver triflate-catalyzed three-component reaction of 2-alkynylbenzaldehyde, sulfonohydrazide, and α,β-unsaturated carbonyl compound is reported, which affords H-pyrazolo[5,1-a]isoquinoline-1-carboxylates, e.g., I in good yield. This study involved multiple reactions and reactants, such as 5-Chloro-2-(phenylethynyl)benzaldehyde (cas: 1186603-47-3Quality Control of 5-Chloro-2-(phenylethynyl)benzaldehyde).
5-Chloro-2-(phenylethynyl)benzaldehyde (cas: 1186603-47-3) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).Quality Control of 5-Chloro-2-(phenylethynyl)benzaldehyde
