An initial emission at 615 nm detected by irradiating Pd(PPh 3 ) 2 (N 3 ) 2 at 77 K is explained by assuming a photochemical cis/trans isomerizationQuenching experiments have been performed by using Ru(bpy) 3 Cl 2 , Os(bpy) 3 Cl 2 , Re(CO) 3 (phen)Cl and Cr(bpy) 3 (ClO 4 ) 3 as sensitizers and the mixed-ligand complexes under discussion as quenchers.
摘要通过电子光谱法对ML n(N 3)2型混合配体配合物(MNi,Pd,Pt; L =膦配体和二膦配体; n = 1、2)的光解进行了吸收,发射的监测。和激发。这些配合物的初始量子产率在CH 2 Cl 2和EtOH中根据辐照波长进行测量。Pd和Pt的光化学形成的MOI n片段的特征在于在77 K下检测到强烈发射。对于合适的Ni O片段,未观察到发射。通过假设光化学是顺式/反式异构化,解释了通过使用Ru(bpy)3 Cl 2,Os( bpy)3 Cl 2,

sodium chloride is evaluated for the synthesis of nickel(I) complexes from the corresponding nickel(II) dichloride precursors. A variety of complexes with phosphine and bipyridine-type ligands were accessed, although some reactions were found to produce mixtures of nickel(0) and nickel(I), and yields were highly variable. Several new nickel(I) complexes were obtained and characterized using various techniques

We report the synthesis, reactivity studies, and ring-opening polymerization of a tricarba[3]nickelocenophane. The resulting green polynickelocene (5) possesses a -(CH2)(3)- spacer between the nickelocene units and is shown to be of high molecular weight. SQUID magnetometry measurements indicate that 5 is a macromolecular material with an S = 1 repeat unit.

Ligand exchange reaction between NiMe2L2 (L = bpy, PEt3) and ditertiary phosphines Ph2P(CH2)nPPH2 (n = 1−4) and effect of ligand on ease of reductive elimination of C2H6 from NiMe2(Ph2P(CH2)nPPh2)

Reactions of the dimethylnickel(II) complexes NiMe2L2 (L = bpy, PEt3 (bpy = 2,2′-bipyridine)) with diphosphines Ph2P(CH2)nPPh2 (n = 1−4) give NiMe2(Ph2P(CH2nPPh2) (n = 2,3) or produce ethane and Nio-diphosphine complexes (n = 1, 4), depending on the chain length of (CH2)n of the diphosphine ligand employed. The ligand exchange reaction between NiMe2 (bpy) and Ph2P(CH2)3PPh2 (dpp) proceeds through an
