N-(Aryl)pyrrole-2-aldimine complexes of ruthenium: synthesis, structure, and spectral and electrochemical properties

Abstract

Reaction of [Ru(dmso)4Cl2] with N-(4′-R-phenyl)pyrrole-2-aldimines (abbreviated as HL-R; where H depicts the dissociable pyrrole N-H proton and R = OCH3, CH3, H and Cl) in refluxing toluene in the...

Unravelling the kinetics of electro- and photochemical S → O linkage isomerization in Ru(ii)–NHC–DMSO complexes utilised for photoinduced substitution reactions

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14] Because of the labile nature of DMSO ligands, these complexes can readily undergo substitution and become compatible with physiological conditions, which is essential for biomedical applications. [15][16][17][18][19] Other pivotal roles of these complexes have also been explored and include application as suitable precursors 4,[20][21][22][23][24][25][26] for the generation of subsequent derivatives having aqua, 27,28 nitrosyl, [29][30][31] carbonyl, 32 polypyridine, 33 and other aromatic ligands. [34][35][36][37][38][39] In addition, the ambidentate nature of the DMSO ligand of Ru-DMSO complexes and its ability to undergo intramolecular and intermolecular S → O linkage isomerization has been extensively studied.…”
