Versatile synthesis of functionalised dibenzothiophenes via Suzuki coupling and microwave-assisted ring closure.
Amino-substituted biphenyls were obtained by Suzuki cross-coupling of 2,6-dibromoaniline with a phenylboronic acid (substituted with Me, NO(2), OH, OMe or Cl) preferably assisted by microwave irradiation. Conversion of the amino group into a thiol preceded a base-induced intramolecular substitution, also facilitated by microwave heating, to generate the second C-S bond of the target dibenzothio...
متن کاملMicrowave-Assisted Synthesis of Pd Nanoparticles and Catalysis Application for Suzuki Coupling Reactions
A facile and efficient method was developed for the synthesis of highly active palladium nanoparticles (PdNPs) by microwave-assisted chemical reduction. The PdNPs with different morphology were prepared with or without KBr (capping agent) using ethylene glycol (EG) and citric acid (CA) as reducing agent in the presence of polyvinylpyrrolidone (PVP), respectively. The as-prepared PdNPs were char...
متن کاملMicrowave Assisted Synthesis of Some Quinoxaline Derivatives
The high commercial demand for quinoxalines needs a rapid, greener and safer synthetic method among the chemists. A series of quinoxaline derivatives has been synthesized by condensation of diamines and dicarboniles in microwave heating conditions and in solvent free media. This environmentally benign synthetic approach gives us excellent yields (80-90%) in shorter reaction time (3.5 minutes.)....
متن کاملAn Efficient Microwave-assisted Suzuki Cross-coupling Reactions on Quinoline Derivatives in Water and Study the Electronic Effects Thereof
Simple and rapid synthesis of various diversely functionalized unprotected 4-amino-2-chloroquinoline-3-aryl derivatives were synthesized in high yields by Suzuki cross-coupling reaction using microwave irradiation in water and in presence of tetrakis(triphenylphosphine)palladium(0). Electronic effects of o-substituted functional groups on the reaction were studied conclusively.
متن کاملSynthesis of [6.6]Metacyclophane via the Suzuki Coupling.
Cyclophane chemistry has contributed greatly to the understanding of fields as varied as molecular and cationic recognition to fundamental principles of NMR.2 To date, the largest all-carbon [n.n]metacyclophane prepared is [5.5]metacyclophane, which was synthesized by the acid-catalyzed dimerization of δ-2-methoxyphenylvaleric acid, yet no conformational information is available about this syst...
