EPR has been used to study the oxidative coupling reaction of aniline, resulting in azobenzene, catalyzed in homogeneous phase by Cupy 4(NO 3) 2 (py = pyridine). Addition of aniline to the catalytic complex results in the progressive reduction of Cu(II) to Cu(I) which, in turn can be...
Selective copper-promoted cross-coupling reaction of anilines and alkylboranesamines (benzene compounds)hydroboration, borationaddition reactionsamination, N‐alkylation, N‐arylationExtension of the Chan–Lam N-alkylation of anilines by using alkylboranes as organoboron partners is reported. Alkylboranes...
2) palladium-catalysed cross-coupling reaction Pd催化偶联反应 1. In palladium-catalysed cross-coupling reaction of aniline iodide and N,N-Dimethyl butyryl silane,reaction condition was strict because of needed-78℃. 在早期的合成方法中,Fischer吲哚反应产率很低;在由碘代胺与酰基硅烷经Pd催化偶联反应...
Ethanol formation during the coupling reaction between silica and silane is another problem. Improving silica compound processing: optimization of the mixing equipment Coupling Reaction Between Aniline and the Epoxide Groups Oxidative graft polymerization of aniline on Si(100) surface modified by plasma pol...
reported that Cu NPs obtained by reducing CuSO4·5H2O with ascorbic acid in lemon juice were encapsulated in zeolite Y and effectively catalyzed the CN coupling reaction of aniline and aryl halide (116). CuNPs/zeolite-Y yield reached 95% compared to Cu NPs (68%) in the reaction of aniline...

Efficient and practical: The title reaction provides an efficient route to -ketoamides compounds, which are ubiquitous structural units in a number of biologically active compounds. N-substituted anilines are suitable substrates for this transformation. Two CH bonds as well as one CH and one NH ...
oxidative cross-couplingphthalocyaninesWe describe a mild procedure for the oxidative C-C cross-coupling of tertiary anilines with phenols which provides the products generally in high yields and with excellent selectivity. The reaction is catalyzed by the hexadecafluorinated iron-phthalocya-nine complex...
INTERNAL ARYL-ARYL COUPLING REACTION USING A NOVEL AND HIGHLY ACTIVE PALLADIUM REAGENT PREPARED FROM Pd(OAc)_2,DPPP, and Bu_3P A novel Pd reagent prepared from equimolar Pd(OAc)_2,DPPP, and Bu_3P (method B) was useful for the internal biaryl coupling reaction of not only triflate-a......
Increasing the reaction temperature caused undesired side reactions, as evi- denced by small additional peaks in HPLC measure- ments. The predominant formation of diphenylamine might be caused by both the effect of high polarity of the solvent and the feed ratio of aniline and bromoben- zene (...
