Synthesis of H-Pyrazolo[5,1-a]isoquinolines via Copper(II)-Catalyzed Oxidation of an Aliphatic C-H Bond of Tertiary Amine in Air was written by Li, Shaoyu;Wu, Jie. And the article was included in Organic Letters in 2011.Formula: C15H9ClO The following contents are mentioned in the article:
A multicomponent reaction of 2-alkynylbenzaldehyde, sulfonohydrazide, and tertiary amine is discovered, which generates the unexpected H-pyrazolo[5,1-a]isoquinolines, e.g., I in good yields under mild conditions. In the reaction process, silver(I)-catalyzed intramol. cyclization and copper(II)-catalyzed oxidation of an aliphatic C-H bond of tertiary amine in air are involved. This study involved multiple reactions and reactants, such as 5-Chloro-2-(phenylethynyl)benzaldehyde (cas: 1186603-47-3Formula: C15H9ClO).
5-Chloro-2-(phenylethynyl)benzaldehyde (cas: 1186603-47-3) belongs to organic chlorides. Organic chlorides can be used in production of: PVC, pesticides, chloromethane, teflon, insulators. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Formula: C15H9ClO
