Heteroleptic neutral Ru(II) complexes based photodiodes

The two complexes Ru(II) containing 2,6-bis(benzimidazol-2-yl)pyridine and 2-pyridine and 2-quinoline carboxylates were synthesized to fabricate organic photodiodes. The electrical properties of Au/Ru(II) complex (I)/n?Si/Al and Au/Ru(II)complex (II)/n?Si/Al diodes were investigated by current-voltage and capacitance-voltage measurements. The fabricated devices give a high rectification behavior with rectification ratio of 2.4 ¡Á104 ?2.1 ¡Á103 at ¡À4 V. The diodes exhibited a high photoconductivity based on trap levels within band gap. The series resistance and barrier height were calculated from (C?V) measurements and compared to other of (I?V). The obtained results indicate that the prepared photodiodes can be used as photosensor for optoelectronic applications.

The Enantioselective Synthesis of Chiral Carbocyclic Nucleosides via Palladium-Catalyzed Asymmetric Allylic Amination of Alicyclic MBH Adducts with Purines

The enantioselective synthesis of carbocyclic nucleosides through the palladium-catalyzed asymmetric allylic amination of alicyclic Morita-Baylis-Hillman (MBH) adducts with purines was successfully developed. With a combination of Pd2(dba)3/L7 as catalyst, various optically active carbocyclic nucleosides featuring a C=C double bond in the carbocycle moiety were obtained in high yields (up to 97%) with excellent N9/N7-selectivities (>95/5) and enantioselectivities (up to >99.6%). In addition, these nucleoside analogs allowed for rapid transformation to a variety of other interesting structurally diverse chiral carbocyclic nucleosides. (Figure presented.).

Selectivity in reductive elimination and organohalide transfer from methyl(aryl) benzylpalladium(IV) complexes of bidentate nitrogen donor ligands, PdBrMe(Ar) (CH2Ph) (L2)

Oxidative addition of iodoarenes to bis(dibenzylideneacetone)palladium(0) in the presence of N, N, N?, N?-tetramethylethylenediamine (tmeda) affords PdIAr(tmeda) (Ar = 4-MeC6H4, 4-MeOC6H4, 4-Me(O)CC6H4, 4-O2NC6H4, 3-MeOC6H4) in high yield. Some of these complexes (Ar = 4-MeC6H4, 4-MeOC6H4, 3-MeOC6H4) react with LiMe to form PdMeAr(tmeda), and the methyl(aryl)palladium(II) complexes react with 2,2?-bipyridyl (bpy) or 1,10-phenanthroline (phen) to afford PdMeAr(L2); PdMePh(phen) may be obtained similarly. All of the diorganopalladium(II) complexes of bpy and phen react with benzyl bromide to form PdBrMeAr(CH2Ph)(L2) but a complex could not be isolated for Ar = 3-MeOC6H4, L2 = bpy. The isolated palladium(IV) complexes react with PdMe2(bpy) at -20C in (CD3)2CO to selectively transfer benzyl bromide to give PdMeAr(L2) and PdBrMe2(CH2PhXbpy) respectively. The complexes PdBrMeAr(CH2Ph)(bpy) (Ar = Ph, 4-MeC6H4, 4-MeOC6H4) undergo selective reductive elimination of Ar-Me in CDCl3 to form PdBr(CH2Ph)(L2), but PdBrMeAr(CH2Ph)(phen) (Ar = Ph, 4-MeC6H4, 4-MeOC6H4, 3-MeOC6H4) give mixtures of PdBr(CH2Ph)(phen) and Me-Ar together with lesser amounts of PdBrMe(phen) and Ar-CH2Ph (ca. 10-20%).

Selective oxidative carbonylation of amines to oxamides and ureas catalyzed by palladium complexes

A new process for converting secondary amines into N,N,N?,N?- tetraalkyloxamides under CO pressure, catalyzed by homogeneous palladium complexes in the presence of 1,4-dichloro-2-butene (DCB) as an oxidant, has been developed. The mechanism of the oxidative double-carbonylation process, consisting of the oxidation of Pd(0) to Pd(11) with DCB through a beta-chloride elimination of the eta3-(chloromethyl) allylpalladiuni(11) intermediate, the formation of mono- and bis(carbamoyl)palladium species, and a reductive elimination of the two carbamoyl ligands, is proposed based on studies of the behavior of carbamoylpalladium complexes. When primary amines are employed with DCB as the oxidant, N,N?-dialkyloxamide is catalytically produced, whereas urea is exclusively produced when iodine is used as the oxidant. The reaction of an N-monopropylcarbamoylpalladium complex with propylamine under CO gave N,N?-dipropylurea, whereas a treatment with diethylamine yielded unsymmetrical N,N-diethyl-N?-propylurea, implying the intermediate formation of propyl isocyanate that is converted into the urea upon a reaction with the added amine. A kinetic study on the reaction of chloro-N- propylcarbamoylpalladium with triethylamine suggested a process proceeding through a base-promoted dcprolonalion of the N-monoalkylcarbamoyl ligand to form propyl isocyanate.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Mechanistic study of the Pd/TOMPP-catalyzed telomerization of 1,3-butadiene: Influence of aromatic solvents on bis-phosphine complex formation and regioselectivity

A study of the influence of reaction conditions on the Pd/TOMPP-catalyzed (TOMPP = tris(2-methoxyphenyl)phosphine) telomerization of 1,3-butadiene with phenols revealed that the composition of the reaction medium strongly influences the regioselectivity of the telomer products. Mechanistic studies show this effect to be related to the stability of the key catalytic intermediate cis-[Pd((1-3eta)-octa-2,7-dien-1-yl)(TOMPP)2]+ (E), which mainly depends on the solvent composition. The crotyl analogue cis-[Pd((1-3eta)-but-2-en-1-yl)(TOMPP)2]BF4 (4) was synthesized as a model for E and was fully characterized, including by an X-ray crystal structure determination. Comparison of the crystal structures of 4 and [Pd((1-3,7,8eta)-octa-2(E),7-dien-1-yl)(TOMPP)]BF4 (1), an analogue of intermediate C, shows that the difference in regioselectivity for nucleophilic attack of these complexes is not reflected in the structure of the allyl moiety. Furthermore, Pd/TOMPP-catalyzed n/iso equilibration reactions of telomers show that all product formation routes in the Pd-catalyzed telomerization mechanism are reversible. Telomer product equilibration studies resulted in complete conversion to 1,3,7-octatriene, with the selectivity changing over time in favor of formation of the Z isomer of octatriene.
