Versatile chiral palladium(II) complexes for enantiomeric purities of 1,2-diamines

Cyclometallated complexes derived from pyrimidin- and pyridazinehydrazones: Structural evidence of intermolecular “chelate metal ring” π–π interactions

“…These compounds are usually classified according to the metal, to the donor atom, or to chelate ring size; by far the most well-studied examples are five-membered palladacycles containing nitrogen-Pd and C(phenyl)-Pd bonds [1][2][3][4][5][6][7][8][9]. They exhibit a good number of applications which range from the synthesis of new organic and organometallic compounds, to mesogenic species and catalytic materials [10][11][12][13][14][15][16][17][18][19][20][21][22] as well as promoting unusual coordination environments [23].…”

Cyclometallation of phenylhydrazones: Synthesis, reactivity, crystal structure analysis and novel trinuclear palladium(II) cyclometallated compounds with [C,N,N′] terdentate ligands

“…The cyclometallation reaction, i.e., the intramolecular activation of aromatic C-H bonds of coordinated ligands by transition metals, has been widely investigated [1][2][3][4][5]. They exhibit a good 0022 number of applications which range from the synthesis of new organic and organometallic compounds, to mesogenic species and catalytic materials [6][7][8][9][10][11][12][13][14] as well as promoting unusual coordination environments [15].…”

Novel Enantioselective Synthesis of Functionalized Pyridylarsanes by a Chiral Palladium Template Promoted Asymmetric Hydroarsanation Reaction

“…Melting points were measured using the SRS Optimelt Automated Melting Point System, SRS MPA100. The enantiomerically pure forms of the complexes (R c )-1, (S c )-1, [19] (E)-1-phenyl-3-(pyridin-2-yl)-2-propenone, [20] and methyl (E)-1-methyl-3-(pyridin-2-yl)-2-propenoate [21] were prepared as previously reported.
