1,3-Diarylimidazolidin-2-ylidene (NHC) complexes of Pd(II): Electronic effects on cross-coupling reactions and thermal decompositions

N‐heterocyclic carbene complexes of Rh(I) and electronic effects on catalysts for 1,2‐addition of phenylboronic acid to aldehydes

“…The structurally and sterically similar 1,3-bis(2,6-dimethylphenyl)imidazolinium salts containing H, CH 3 , Br and Cl groups are known in the literature. [12] Rh-NHC complex (4) was obtained [16 -21] Thus, the carbonyl complexes of type 5 have been synthesized by replacing the COD ligand with excess CO.…”

“…[11] In a recent study on the complexes (I), we observed that the variation of the p-substituents (X) has a significant influence on the catalytic behavior of the Suzuki coupling of NHC-Pd complexes. [12] Only a few references referring to 4,5-substituted imidazol(in)-2-ylidene ligands can be found in the literature. [13] On the other hand, the rhodium-catalyzed 1,2-addition of aryl boronic acids has also enjoyed significant development: in situ formed and preformed NHC complexes of rhodium have been successfully applied to 1,2-arylations of aldehydes.…”

Flexible Analogues of Azaindole DYRK1A Inhibitors Elicit Cytotoxicity in Glioblastoma Cells

“…[14] To a solution of glyoxal (40 % in ethanol, 0.9 equiv.) in ethanol (0.10 M) was added amine 16a-b (1.1 equiv.…”

“…The spectroscopic data matched those reported in the literature. [17] N-(3-(4-(Benzyloxy)phenyl)propyl)-5-bromopyridin-2-amine (14) This compound was prepared according to General Procedure B. 4-(6-((3-(4-Hydroxyphenyl)propyl)amino)pyridin-3-yl) phenol (2d) To a solution of 15 (1.0 equiv., 0.1 mmol) in MeOH (5 mL) was added Pd/C (10 wt-%, 5 mg) under a nitrogen atmosphere, and the mixture was stirred at room temperature for 2 h under 1 atm of H 2 .…”

Synthesis, Characterization and Coordination Chemistry of N,N'-bis(3-pyridylmethyl)benzene-1,4-dicarboxamide with Palladium and Ruthenium Salts

“…The complex based on palladium transiton-metal currently interest because its properties suitable for catalytic applications [11]. Vouti [12] stated the interaction between ligand and metal centre influence the chemical behaviour of a metal ion and its properties as a metal complex. Meanwhile, the special band was detected at 499.77 cm -1 for complex 3.…”
