ChemInform Abstract: Synthesis of Chiral 2-Arylpropenoic Esters by the Palladium Catalyzed Carbonylation of Arylacetylenes

Autor: Vanessa Gasparini, Adriano L. Monteiro, Vanusa R. Lando

Publikováno v: ChemInform. 28

A simple method is described for the synthesis of chiral 2-arylpropenoic esters by carbonylation of arylacetylenes in the presence of chiral alcohols catalyzed by palladium complexes under mild conditions (10 atm, 100°C, 2h) with high yields.

ChemInform Abstract: NiCl2(PCy3)2: A Simple and Efficient Catalyst Precursor for the Suzuki Cross-Coupling of Aryl Tosylates and Arylboronic Acids

Autor: Vanusa R. Lando, Adriano L. Monteiro, Danilo Zim, Jairton Dupont

Publikováno v: ChemInform. 33

NiCl2(PCy3)2 associated with PCy3 promotes the selective cross-coupling of aryltosylates with arylboronic acids under relatively mild reaction conditions, and a variety of functional groups are tolerated in both arenes. This is one of the simplest an

Homocoupling of aryl iodides and bromides promoted by sulfur-containing palladacycles

Autor: Adriano L. Monteiro, Priscila B. Silveira, Jairton Dupont, Vanusa R. Lando

Publikováno v: ResearcherID

Sulfur-containing palladacycles, in particular those derived from the orthometalation of benzylthioethers, effectively promote the homocoupling of aryl iodides and bromides, under relatively mild reaction conditions to furnish symmetrical biphenyls i
