A new series of PdII complexes derived from thiosemicarbazone has been synthesized. The synthesized PdII complexes have been characterized on the basis of elemental analyses, FT-IR, ¹H- and ¹³C-NMR, UV/VIS, and thermal studies. A square-planar geometry has been assigned around PdII ions on the basis of results obtained from UV/VIS studies. The thiosemicarbazone ligand and its PdII complexes hav...

Cyclic glyoxalcarbohydrazone[(1,2,4,5,8,9,11,12-octaazacyclotetradeca-5,7,12,14tetraene-3,10-dione) = (glyozalcarbzH)2] complexes of Ni II, PdII, CoII, ZnII and CdII of composition M (glyoxalcarbzH)2X2nH2O (M = Ni II, PdII, CoII,ZnII or CdII and X = Cl> , 1/2 SO4 -2 and n = 0,1 or 4) have been isolated by refluxing appropriate metal salts with glyoxal and carbohydrazide in requisite proportion ...

The direct functionalization of carbon-hydrogen (C-H) bonds has emerged as a versatile strategy for the synthesis and derivatization of organic molecules. Among the methods for C-H bond activation, catalytic processes that utilize a PdII/PdIV redox cycle are increasingly common. The C-H activation step in most of these catalytic cycles is thought to occur at a PdII centre. However, a number of ...

1,2,3-Ferrocenyl triazole ligands generated by click reactions in dendrimers bind Pd(OAc)2 with a systematic one-to-one stoichiometry as monitored by titration using the ferrocenyl redox sensor attached to the triazole ring, and the dendritic PdII complexes formed are best reduced by methanol to form palladium nanoparticles of designed types and sizes that show excellent efficiency and selectiv...

The use of weak bases and mild conditions is currently the most sustainable attractive synthetic approach for preparation late-transition metal complexes, some which are widely used in catalysis, medicinal chemistry materials science. Herein, cuprate, aurate or palladate species a continuous flow CuI, AuI PdII-NHC complexes reported. All reactions examined proceed under extremely make technical...

A facile large-scale synthesis of the “push–pull”-substituted ligand bis(diethylamino)(pentafluorophenyl)phosphane is reported. A selenophosphorane as well as complexes with CuI and PdCl2, can be formed almost quantitatively from suitable starting materials. The PdII complex shows a square-planar coordination with significant distortions of the Cl–Pd–Cl moiety in the solid state. In contrast, t...

Abstract: The anionic polymerization of 1-phosphaisoprene [Mes*P=C(Me)−CH=CH2 (E-1)] affords poly(1-phosphaisoprene) 2 in high yield (75%). Concentrated solutions polymer (Mn = 21,800 g mol–1; Đ 1.02) a P-analogue natural rubber, undergo gelation upon treatment with [Pd(cod)Cl2] (0.15 P equiv). Evidence for P-coordination to PdII was obtained by 31P and 1H NMR spectroscopy. is reversed the addi...

Two polyanions [SeI V2 PdII4 WVI14 O56 H]11- and [SeI V4 PdII4 WVI28 O108 H12 ]12- are the first hybrid polyoxometalates in which classical (Group 5/6 metal based) and non-classical (late transition-metal based) polyoxometalate units are joined. Requiring no supporting groups, this co-condensation of polyoxotungstate and isopolyoxopalladate constituents also provides a logical link between POM-...
