Liang, Ran et al. published their research in Organic Letters in 2017 | CAS: 23707-37-1

Isoquinolin-7-amine (cas: 23707-37-1) belongs to isoquinoline derivatives. Although isoquinoline derivatives can be synthesized by several methods, relatively few direct methods deliver the unsubstituted isoquinoline. Other industrial applications include their use as corrosion inhibitors, preservatives, and as solvents for resins and terpenes.Electric Literature of C9H8N2

N-Methylation of amines with methanol catalyzed by a Cp*Ir complex bearing a functional 2,2′-bibenzimidazole ligand was written by Liang, Ran;Li, Shun;Wang, Rongzhou;Lu, Lei;Li, Feng. And the article was included in Organic Letters in 2017.Electric Literature of C9H8N2 This article mentions the following:

A new type of Cp*Ir complex bearing a functional 2,2′-bibenzimidazole ligand, [Cp*IrCl[2,2′-(C7H5N2)2]] was designed, synthesized, and found to be a highly effective and general catalyst for the N-methylation of a variety of amines with methanol in the presence of a weak base (0.3 equiv of Cs2CO3), giving N-methylamines with high chemoselectivity. In the experiment, the researchers used many compounds, for example, Isoquinolin-7-amine (cas: 23707-37-1Electric Literature of C9H8N2).
