Abstract

A series of 20 Schiff base ligands derived from 2-aminothiazole and its derivatives and aryl aldehydes with either [RhCl(PPh3)3] or [Rh(µ-Cl)(COD)]2 in the presence of 4 equivalents of PPh3 lead to an Rh(III) cyclometallated complex and the imine ligand (C-H) bond has been added to the metal (C-M-H). The complexes were investigated by using I.R., 1H, 13C and 31P NMR Spectroscopic techniques. The signal of the (C-H) ligand was observed as trans to the nitrogen atom in the complex which is a donor ligand.

Graphical Abstract:

Total synthesis of hydridothiazole rhodium complexes possessing rhodium hydride signal at δ (-14.60 to-15.04) ppm, trans to N-donor ligand and iminoyl carbon (7C=N) signal in Rh (III) observed at δ (220.1-237.6)ppm, lower field and suggestive of carbine like properties.

Keywords:: Hydrido complexes, ligand substitution, IR,1H,13C,31P NMR, oxidative-addition, phosphine complexes, rhodium, Schiff-bases.

I am completely satisfied with the service I received from Bentham Science Publishers, right from the submission of our research paper in ‘Open Chemistry’ to its publication in the journal. The reviewers' and editor's comments were very helpful in improving the paper.

I take this opportunity to express my appreciation to the whole team of BSP!
