Bis(allenylidene) Complexes of Palladium and Platinum
trans-Bis(alkynyl)palladium complexes, trans-[(PEt3)2Pd(-CtCC{dO}NR2)2] (NR2 = NMe2 (2a), N(CH2)4 (2b)), were synthesized by two different methods: (a) by copper-catalyzed reaction of HCtCC(dO)NR2with [PdCl2(PEt3)2] under basic conditions and (b) by treatingHCtCC(dO)NR2 with AgNO3 followed by transmetalation of the alkynyl ligand from silver to [PdCl2(PEt3)2]. The reaction of AgCtCC(dO)NMe2 (3a...
متن کاملTetrabenzporphyrin Complexes of Iron, Palladium and Platinum
The syntheses and absorption spectra of Fe(II)TBP(pyridine)2, Pd(II)TBP, and Pt(II)TBP (TBP = Tetrabenzporphyrin) are reported. The emission spectra of PdTBP and PtTBP were measured. Both complexes exhibit only phosphorescence from the lowest triplet of TBP. The Fe complex was oxidized to the cation [FeTBP(pyn*dine)J+ which was characterized by its absorption and ESR spectrum. The emission spec...
متن کامل"Inverse-electron-demand" ligand substitution in palladium(0)-olefin complexes.
Ligand substitution reactions are ubiquitous in transition-metal chemistry and catalysis. Investigation of ligand substitution reactions for a series of electron-rich palladium(0)-olefin complexes, (bathocuproine)Pd(nitrostyrene) reveals an unprecedented mechanism in which the metal serves as the nucleophilic partner in an "associative" substitution pathway.
متن کاملsynthesis of binuclear platinum complexes containing biphosphine ligand
هدف از این مطالعه طراحی یک روش کلی برای سنتز یک سری از کمپلکس های دو هسته ای متقارن سیکلومتاله شده پلاتین (ii) بوده که دارای یک لیگاند پل زن(1,2-bis[bis(pentafluoro-phenyl)phosphino]ethane),dfppe, است. از واکنش cis-[pt(r)2(sme2)2]، که در آنr= para-tolyl ، با یک اکی والان از لیگاند benzo[h]quinoline,bhq، در استون محصول [pt(r)(bhq)(sme2)] که در آن r= para-tolyl بدست می آید. همچنین از واکنش 5/0 اک...
N-heterocyclic carbene tethered amido complexes of palladium and platinum.
With a view to applications in bifunctional catalysis, a modular cross-coupling strategy has been used to prepare amine bis(imidazolium) salts (3a and 3b) and an amine mono(imidazolium) salt (6) as precursors to chelating amido-NHC ligands. Treating the pro-ligands 3 with 3 equivalents of the bulky base KHMDS and Pd(OAc)(2) or PtCl(2)(COD) gave the four amido bis(N-heterocyclic carbene) pincer ...
