Substituted Pyrrole‐based Schiff Bases: Effect On The Luminescence Of Neutral Heteroleptic Cu(I) Complexes

“…[6,[17][18][19][20] Further, Schiff bases are useful organic compounds that can easily be synthesized starting from an amine and an aldehyde and are widely applied as mono-and polydentate ligands towards transition metal complexes such as Fe(II), Co(II), Ni(II), Pt(II), Pd(II) and Zn(II). [21][22][23][24][25][26] Hence, neutral Schiff bases were successfully employed for the preparation of photoactive cationic Cu(I) complexes. [27][28][29] Given our interest in luminescent Cu(I) derivatives, [30][31][32][33][34][35][36][37] we deemed it interesting to investigate the effect of substituted pyrrole-based Schiff bases in the photophysical properties of the derived complexes.…”

Five Coordinate Platinum(II) in [Pt(bpy)(cod)(Me)][SbF6]: A Structural and Spectroscopic Study

“…Thus, it is generally assumed that five coordinate Pt(II) complexes with a trigonal bipyramidal geometry might be stable or intermediate species, while square pyramidal species rather have the character of a transition state [2][3][4]. Indeed, most of the structurally-characterized five coordinate Pt(II) complexes exhibit clearly a trigonal bipyramidal geometry [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Interest in five coordinate Pt(II) species and their Pd(II) analogues comes from their involvement as intermediates in important Pt(II) or Pd(II) catalyzed organometallic transformations [3,[21][22][23][24][25][26][27][28].…”

“…Indeed, when reacting the Zeise anion with diimine ligands (N^N), five coordinate complexes [Pt(N^N)(η 2 -C2H4)Cl2] were obtained [48][49][50][51][52][53][54][55][56][57][58][59][60]. The mono-olefin complexes of the type [Pt(N^N)(η 2 -olefin)X2] (X = halogens and pseudohalogens) form indeed the main body of the so far reported organometallic pentacoordinate Pt(II) complexes [4,[5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”

Suzuki–Miyaura Coupling of Aryl Iodides, Bromides, and Chlorides Catalyzed by Bis(thiazole) Pincer Palladium Complexes

“…As five-membered heterocyclic structures, thiazoles can be used as N -donor ligands. However, thiazole-derived tridentate ligands are underrepresented in the chemistry of coordination compounds. , Recently, Odinets and co-workers reported that an unsymmetrical SCN pincer complex, bearing a thiophosphoryl and a benzothiazole ring as donating sites, showed an ability to efficiently promote the SM coupling of chloroacetophenone . Symmetrical pincer structures have many advantages over unsymmetrical ones, such as structural simplicity and synthetic conciseness and convenience.…”
