Journal ArticleDOI
Suzuki–Miyaura cross-coupling reaction of aryl bromides and chlorides with phenylboronic acid under aerobic conditions catalyzed by palladium complexes with thiosemicarbazone ligands
Ioannis D. Kostas,Fotini J. Andreadaki,Dimitra Kovala-Demertzi,Christos Prentjas,Mavroudis A. Demertzis +4 more
TL;DR: For example, in this paper, palladium complexes with salicylaldehyde thiosemicarbazones were applied as catalyst precursors to the Suzuki-Miyaura reaction.
Journal ArticleDOI
A palladium complex with a new hemilabile amino- and sulfur-containing phosphinite ligand as an efficient catalyst for the Heck reaction of aryl bromides with styrene. The effect of the amino group
TL;DR: In this article, a palladium complex with a new hemilabile amino-and sulfur-containing phosphinite ligand has been synthesized and its crystal structure determined, which efficiently catalyses the Heck reaction of aryl bromides with styrene at 130°C after 24h.
Journal ArticleDOI
First use of a palladium complex with a thiosemicarbazone ligand as catalyst precursor for the Heck reaction
Dimitra Kovala-Demertzi,Paras Nath Yadav,Mavroudis A. Demertzis,Jerry P. Jasiski,Fotini J. Andreadaki,Ioannis D. Kostas +5 more
TL;DR: A palladium complex with salicylaldehyde N(4)-ethylthiosemicarbazone has been synthesized and according to its crystal structure the ligand is bound to the metal in an O, N, S-terdentate coordination mode.
Journal ArticleDOI
New Palladium Complexes with S‐ or Se‐Containing Schiff‐Base Ligands as Efficient Catalysts for the Suzuki–Miyaura Cross‐Coupling Reaction of Aryl Bromides with Phenylboronic Acid under Aerobic Conditions
Ioannis D. Kostas,Barry R. Steele,Aris Terzis,Svetlana V. Amosova,Alexander V. Martynov,Natalia A. Makhaeva +5 more
TL;DR: In this paper, four palladium chelate complexes with S- or Se-containing substituted salicylaldehyde Schiff base derivatives have been synthesized, which are thermally and air stable and efficiently catalyze the Suzuki-Miyaura crosscoupling of aryl bromides with phenylboronic acid in air.
Journal ArticleDOI
The first use of porphyrins as catalysts in cross-coupling reactions : a water-soluble palladium complex with a porphyrin ligand as an efficient catalyst precursor for the Suzuki-Miyaura reaction in aqueous media under aerobic conditions
TL;DR: In this article, a palladium complex with a porphyrin ligand was used as a catalyst precursor for cross-coupling reactions in the Suzuki-Miyaura reaction.
