Mixed-ligand (1,2-diimine)(ethylene-1,2-dithiolate) complexes of nickel, palladium, and platinum

synthesis 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...

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...

Tetrabenzporphyrin 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...

Chemistry of Mixed Donor Pincer Ligand Nickel Complexes

Photooxidation of 1,2-Dithiolene Complexes of Nickel, Palladium, and Platinum in Chloroform

The photochemistry of the following 1,2-dithiolene complexes has been investigated. M(S2C2R2)2z: M = Ni, Pd, Pt, R = CN, z = 2-, I-; M = Ni, Pt, R = C6HS, z = 0; M = Ni, R = C&, z = 1-. These complexes were not light sensitive in most solvents such as acetonitrile. Those complexes which are oxidized at potentials between E l / 2 = 0.1 and 0.5 V vs. SCE (M = Ni, Pd, Pt, R = CN, z = 2-; M = Ni, R...
