چکیده

An iterative strategy for the synthesis of new sulfur-functionalized oligothiophenes by Suzuki or Stille cross-coupling reactions was applied to the reaction of 4-bromo-tert-butylphenylthioether with thiophene derivatives. The planarity of the oligothiophenes obtained was confirmed by the singlecrystal X-ray structure analysis of 2-(4′-tert-butylthiophenyl)thiophene, which shows a potentially large electronic conjugation length.

Synthesis of functionalized thiophenes and oligothiophenes by selective and iterative cross-coupling reactions using indium organometallics.

The synthesis of unsymmetrical 2,5-disubstituted thiophenes by selective and sequential palladium-catalyzed cross-coupling reactions of indium organometallics with 2,5-dibromothiophene is reported. Following an iterative coupling sequence, α-oligothiophenes were synthesized in good yields and with high atom economy.

A novel "double-coupling" strategy for iterative oligothiophene synthesis using orthogonal Si/Ge protection.

[reaction: see text] A new iterative synthesis of regioregular oligothiophenes has been developed in which "double-coupling" after each iteration minimizes deletion sequences. The method exploits the susceptibility of alpha-silyl- but not alpha-germyl-substituted thiophene derivatives toward nucleophilic ipso-protodemetalation and features an unusual "base-free" Suzuki-type cross-coupling proto...

Synthesis, Characterization and Catalytic Activity of Ligand Stabilized Palladium Nanoparticle: A Catalyst Compliment to the Heck Coupling Reaction

The palladium metal is the most frequently used metal because of its excellent catalytic efficiency and most flexible varying oxidation state. So,  we report  that palladium nanoparticles (Pd NPs) stabilized by a ligand (o-vanilindiphenylethanedionedihydrazone, L)  using reverse micelles method have been synthesized, while all particles are in spherical shape and ranging between 10 and...

Synthesis of novel tridentate ligand-based palladium catalyst and investigation of its reactivity towards Suzuki, Sonogashira and Heck coupling reactions

We have demonstrated a simple and efficient route for the synthesis of a novel imine based tridentate ligand and its Pd-complex to investigate the C-C cross-coupling reactions, that involve column chromatography purification in only one step. The catalytic activity of the newly synthesized catalyst was studied for the Suzuki, Sonogashira and, Heck cross-coupling reactions under mild conditions....
