Synthesis, Characterisation and Catalytic Studies of Iron(III), Cobalt(II), Nickel(II) and Copper(II) Complexes Containing N,O Donor Ligands and Triphenylphosphine

Reactions of Trimethylphosphane‐Supported Cobalt Complexes with Salicylaldimines – Formation and Structures of Cobalt Compounds Containing Salicylaldiminato [N:O] Ligands

“…[22] Recently, we have introduced the salicylaldimine ligands, which are isoelectronic to 2-diphenylphosphanylbenzaldehyde. We now report the reactions of electron-rich, lowvalent cobalt complexes CoMe(PMe 3 ) 4 , CoCl(PMe 3 ) 3 and Co(PMe 3 ) 4 with salicylaldimines, which have afforded tetrahedral bis(chelate) cobalt(II) imine complexes (7)(8)(9)(10)(11)(12), an oc- tahedral tris(chelate) cobalt(III) imine complex 13 as well as a π-coordinate imine complex 15, which includes trimethylphosphane as a supporting ligand. The neighbouring N-donor of the salicylaldimine ligand plays an active part in the formation of these complexes .…”

“…[1][2][3][4][5][6] Large numbers of complexes of transition metals with Schiff bases, which are used as agents in organic synthesis, catalysts and anticancer or antitoxin drugs, have been synthesized and studied in many laboratories. [7][8][9][10][11][12] Recent progress has been made in the study of Schiff base-Co(II) complexes as dioxygen carriers. These reports have considerable significance in chemical and biochemical processes.…”

Synthesis, characterization and catalytic activity of polymer anchored transition metal complexes toward oxidation reactions

“…. The far IR spectrum of these complexes exhibits a broad intense band around 315-336 cm -1 , which may be assigned to M-Cl [23].…”

Selective oxidation of olefins and aromatic alcohols with tert‐butylhydroperoxide catalyzed by polymer‐anchored transition‐metal complexes

“…2 showed ν M Cl characteristic frequencies at 330 and 315 cm −1, respectively. 40 The far IR spectrum of Cat. 3 exhibited a broad intense band around 332 cm − 1 ; this was assigned to υPdCl bridge .…”
