A new family of σ-aryl ruthenium(iii) complexes [Ru(L1-4)(PPh3)2Cl] (1-4) (where L1H2 = N-(quinolin-8-yl)benzamide for 1, L2H2 = 4-chloro-N-(quinolin-8-yl)benzamide for 2, L3H2 = 4-nitro-N-(quinolin-8-yl)benzamide for 3, L4H2 = 3-nitro-N-(quinolin-8-yl)benzamide for 4 and H = dissociable protons) derived from bidentate ligands having amide bonds was synthesized through C-H bond activation. These organometallic ruthenium(iii) complexes were treated with nitric oxide (NO) to afford the nitrosyl complexes [Ru(NO2L1-4)(PPh3)2(NO)](ClO4) (1a-4a) (where NO2L1H2 = N-(5-nitroquinolin-8-yl)benzamide for 1a, NO2L2H2 = 4-chloro-N-(5-nitroquinolin-8-yl)benzamide for 2a, NO2L3H2 = 4-nitro-N-(5-nitroquinolin-8-yl)benzamide for 3a, NO2L4H2 = 3-nitro-N-(5-nitroquinolin-8-yl)benzamide for 4a and H = dissociable protons). All ruthenium complexes were characterized by various spectroscopic techniques. An X-ray crystallographic study afforded the molecular structure of complex 4a and the site-specific orthometallation was scrutinized. The coordinated NO molecule was found to be photolabile under visible and UV light.

The palladium-catalyzed ortho-selective chlorination of N-quinolinylbenzamide derivatives with hydrochloric acid was achieved under anodic oxidation conditions. The use of 5,7-dichloro-8-quinolinyl group as directing group was effective for the selective
Palladium-catalyzed aminocarbonylation of aryl iodides with amines: efficient access to bidentate amide directing groups

A new route to bidentate amide directing groups has been developed via the palladium(II)-catalyzed aminocarbonylation. Under atmospheric carbon monoxide pressure, using commercially available aryl iodides and aromatic amine derivatives as substrates, the three-component reaction proceeded smoothly to give the desired products in moderate-to-excellent yields with good functional-group compatibility.
C-H Amidation and Amination of Arenes and Heteroarenes with Amide and Amine using Cu-MnO as a Reusable Catalyst under Mild Conditions

An atom-economical and efficient route for the direct amidation and amination of aryl C-H bonds using our synthesized recyclable heterogeneous Cu-MnO catalyst is reported here. The direct C-H amidation was carried out using a simple amide without any prea

In this paper, Ni(II)- Catalyzed ortho-amidation of C(sp2)-H bond with sulfonyl azides directed by (quinolin-8-yl) amine (AQ-amine) is described. The method provides a straightforward method for the synthesis of sulfonamides from available sulfonyl azides via the transition-metal-catalyzed C(sp2)-N bond forming reaction. The amidation reactions exhibit high functional group compatibility, which might proceed a Ni(III)/Ni(I) catalytic cycle. We also applied sulfonamide compound in OLEDs, which exhibits the certain application potential in OLEDs field.
