Synthesis and Properties of Ethene-Bridged Terthiophenes

A method for the facile synthesis of ethene-bridged terthiophenes (EBTTs) in two steps has been developed. The first step is a double Sonogashira coupling between 3?,4?-dibromo-2,2?:5?,2?-terthiophene and terminal alkynes to give dialkynylated terthiophenes, and the second step is a cyclization reaction to afford EBTTs. The fundamental physical properties of EBTTs were also studied.

One of the oldest and most widely used commercial enzyme inhibitors is aspirin, SDS of cas: 72287-26-4, which selectively inhibits one of the enzymes involved in the synthesis of molecules that trigger inflammation. you can also check out more blogs about 72287-26-4

Self-Assembly Process of a Pd2L4 Capsule: Steric Interactions between Neighboring Components Favor the Formation of Large Intermediates

The effect of molecular interactions between the components on the self-assembly process of Pd2L4 structures was investigated by a 1H NMR-based quantitative approach (QASAP: quantitative analysis of self-assembly process). Although the self-assembly of the Pd2L4 cage without interactions between the bent ligands took place, mainly producing small intermediates, the self-assembly of the Pd2L4 capsule composed of bent ligands with anthracene panels tends to produce large intermediates containing more components than the capsule. This is ascribed to steric interactions between the panels.

Functionalized homoleptic cis- and trans-C,N-ortho-chelated aminoaryl platinum(II) complexes

For the synthesis of corner building blocks with a 90 angle, to be used for the construction of larger structures, several homoleptic platinum(II) complexes [Pt(eta2-C,N)2] (10-14), as both cis- and trans-isomers, have been prepared starting from newly synthesized ortholithiated (dimethylamino)methyl arene ligands. The aryl groups of these arylplatinum(II) complexes contain additional substituents such as halides or methyl, naphthyl, or (dimethylamino)methyl groups. With these functionalities on the aryl rings the cis/trans ratio could be tuned. The presence of steric groups ortho to the metal center (methyl or naphthyl) favors the formation of planar-chiral cis-isomers. The trans-isomers isomerize irreversibly to the thermodynamically favored cis-isomers upon heating. The arylplatinum(II) complexes were used in various substitution reactions. Addition of a stronger coordinating ligand changes the denticity of the C,N-attached ligands. The halide functionalities were exploited for chemoselective lithiation and subsequent transmetalation reactions in order to synthesize the SnMe3-functionalized [Pt(C,N)2] complexes. A Suzuki-Miyaura C-C coupling reaction on one of these complexes was also performed, resulting in the preparation of a mixed trinuclear palladium/platinum complex (25). The crystal structure determinations of four functionalized cis-[Pt(C,N)2] complexes, cis-12¡¤Et2O, cis-14¡¤xC6H6, 19, and 25¡¤xCH2Cl2, are reported. With these structures it is shown that depending on the substituents, the degree of planarity around the platinum center can be tuned.

Direct arylation polymerization: A guide to optimal conditions for effective conjugated polymers

The rapid increase in the breadth and scope of transformations that involve metal-promoted activation of C?H bonds is fundamentally changing the field of synthetic chemistry. Direct arylation polymerization is a newly established synthetic protocol for atom economical, effective, and affordable preparation of conjugated polymers, which continue to be incredibly advantageous as operative materials for a diverse and continually evolving array of applications. This route toward conjugated polymers for high performance materials is particularly appealing because it circumvents the preparation of organometallic derivatives and the associated cryogenic air- and water-free reactions. Although a broad range of monomers are now readily polymerizable, direct arylation polymerization is known to produce defects in the chemical structure, which have a strong impact on the optical, electronic, and thermal properties of conjugated polymers. Fundamental understanding of the underlying considerations when employing different reaction protocols is required to truly enable a broad reaching platform.

Bipolar host materials for green triplet emitter in organic light-emitting diodes

We have developed novel bipolar host materials for high efficiency green phosphorescent OLEDs (PHOLEDs). Phenyl moieties were inserted in a 9,9?-(biphenyl-4,4?-diyl)dicarbazole (CBP) compound to provide much easier electron injection and to increase electron mobility. The efficiency increase and voltage reduction by this modification were observed in green PHOLEDs. At a given constant luminance of 1000 cd/m2, the power efficiency was enhanced about twenty percent in the general green PHOLED devices. Copyright

Room temperature C-H activation and cross-coupling of aryl ureas in water

(Chemical Equation Present) Just mix in water’n stir: Pd-catalyzed C-H activation/cross-couplings can be carried out at room temperature in water/surfactant mixtures. The combination of Pd-(OAc)2 and HBF 4 allowed for reactions of aryl ureas with aryl iodides under very mild conditions, using micellar catalysis (see scheme). This reaction is made possible by use of an in situ generated cationic palladium catalyst.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: catalyst-palladium, you can also check out more blogs about21797-13-7

Investigation of Heck coupling on 6-bromo[2,3-d]thienopyrimidines for construction of new EGFR inhibitor lead structures

With the aim of identifying new lead structures for EGFR inhibition, a study of palladium catalysed Heck coupling between (R)-6-bromo-N-(1-phenylethyl)thieno[2,3-d]pyrimidin-4-amine and various acrylates was performed. The Heck coupling was highly dependent on type of catalyst, solvent, base type and the use of tetrabutylammonium chloride as additive. The products were stable in the dark, but underwent trans-cis isomerization upon exposure to light. Kinase profiling indicate that acrylates grafted on the [2,3-d]thienopyrimidines is an attractive scaffold for identification of potent and highly selective EGFR inhibitors.

Regioselective hydroesterification of 1-alkynes catalyzed by palladium- phosphine complexes

The reaction of 1-alkynes, CO, and methanol (hydroesterification) catalyzed by palladium-phosphine complexes has been studied in acetonitrile media. Branched alpha,beta-unsaturated ester was mainly produced in the presence of a catalytic amount of a palladium complex containing PPh3. In contrast, dppf-based palladium complexes showed excellent regioselectivity for the formation of linear alpha,beta-unsaturated ester. On the other hand, hydroesterification of 1,7-octadiyne with a catalyst system of Pd(OAc)2/PPh3/TsOH followed a different path to give a cyclized carbonylation product aS the major product. A tentative mechanism involving a PdH species has been proposed for these reactions. (C) 2000 Elsevier Science B.V.
