Iron-catalyzed synthesis, structure, and photophysical properties of tetraarylnaphthidines

We describe the synthesis and photophysical properties of tetraarylnaphthidines. Our synthetic approach is based on an iron-catalyzed oxidative C–C coupling reaction as the key step using a hexadecafluorinated iron–phthalocyanine complex as a catalyst and

Nickel-Catalyzed Amination of Aryl Nitriles for Accessing Diarylamines through C?CN Bond Activation

A nickel-catalyzed amination to access diarylamines has been developed through C?CN bond activation of aryl nitriles with anilines. In this developed catalytic protocol, various aromatic and heteroaromatic nitriles could be utilized as the electrophiles to couple with substituted anilines. A diversity of diarylamines were obtained in 15–95% yields. (Figure presented.).

Sonogashira-Hagihara and Buchwald-Hartwig cross-coupling reactions with sydnone and sydnone imine derived catalysts

Seven different palladium complexes of sydnones and sydnone imines and a co-catalyst system consisting of lithium sydnone-4-carboxylate and Pd(PPh3)4 catalyzed Sonogashira-Hagihara reactions between (hetero)- aromatic bromides and 2-methylbut-3-yn-2-ol (52 examples, up to 100% yield). The co-catalyst system and a sydnone Pd complex were also tested in Buchwald-Hartwig reactions (9 examples, up to 100% yield). (Equation Presented).

Electron-Catalyzed Coupling of Magnesium Amides with Aryl Iodides

An electron was found to catalyze the coupling of magnesium diarylamides with aryl iodides giving triarylamines through a radical-anion intermediate. The transformation requires no transition metal catalysts or additives, and a wide array of products are formed in good-to-excellent yields.

PROBLEM TO BE SOLVED: To provide a method for producing a triarylamine compound by coupling an N, N-dialkyl sulfamate compound and a diaryl amide compound in the presence of a nickel catalyst.SOLUTION: A triarylamine is produced by allowing an N, N-dialkyl sulfamate represented by formula (1) (in the formula, Arrepresents a phenyl group or the like, and Rand Reach independently represents a 1-4C alkyl group that may be substituted with a fluorine atom) to react with a diarylamide in the presence of a nickel catalyst.

Solvent-Free Buchwald-Hartwig (Hetero)arylation of Anilines, Diarylamines, and Dialkylamines Mediated by Expanded-Ring N-Heterocyclic Carbene Palladium Complexes

A highly efficient solvent-free protocol for the Buchwald-Hartwig (hetero)arylation of anilines, diarylamines, and dialkylamines mediated by the expanded-ring N-heterocyclic carbene palladium complex (THP-Dipp)Pd(cinn)Cl [THP-Dipp = 1,3-bis(2,6-diisopropylphenyl)-3,4,5,6-tetrahydropyrimidin-2-ylidene; cinn = cinnamyl, 3-phenylallyl] was developed. The catalytic protocol was efficient for the coupling of amines and (hetero)aryl chlorides and bromides bearing donor, acceptor, and bulky substituents.
