- Mononuclear, dinuclear and polymeric 1D thiocyanato- and dicyanamido-copper(II) complexes based on tridentate coligands
-
Three mono-nuclear copper(II) complexes: [Cu(mpipy)(NCS)2] (1); [Cu(mpiq)(NCS)2] (2); [Cu(bdmpzpy)(dca)2(H2O)] (4) a dinuclear, [Cu2(dmenim)2(μ1,3-NCS) 2](ClO4)2 (3) and a linear 1D {[Cu(mpiq)(μ1,5-dca)]ClO4}n (5) complex were synthesized using a variety of tridentate amine ligands (mpipy = N-methyl-N-(2-pyridylmethyl)piperazine; mpiq = N-methyl-N-(2-quinolylmethyl)- piperazine); bdmpzpy = 2,6-bis[(2,5-dimethyl-1H-pyrazolyl)methyl]pyridine; dmenim = Schiff base condensation of N,N-dimethylethylenediamine and imidazole-4(5)-carboxaldehyde). The complexes were characterized by spectroscopic techniques and by single crystal X-ray crystallography. The N-thiocyanato mode of bonding in 1 and 2, the terminal monodentate nitrile-dca bonding in 4, and the bridging modes μ1,3-SCN in 3 and μ1,5-dca in 5 as well as the distorted square pyramidal geometries around the central Cu(II) ions in compounds 1-3 and 5, and distorted octahedral in 4 were confirmed. The magnetic susceptibilities of compounds 3 and 5, investigated at variable temperature (2-300 K), revealed their weak antiferromagnetic coupling nature.

A direct C-H functionalization approach to produce aryl(azaaryl)methylamines from azaarylmethylamines without directing groups is described. Under conditions where the azaarylmethylamines' C-H is reversibly deprotonated, a Pd(OAc)2/NIXANTPHOS-b
