On January 28, 2013, Koreeda, Tetsuro; Kochi, Takuya; Kakiuchi, Fumitoshi published an article.Formula: C12H14F3NO2 The title of the article was Substituent Effects on Stoichiometric and Catalytic Cleavage of Carbon-Nitrogen Bonds in Aniline Derivatives by Ruthenium-Phosphine Complexes. And the article contained the following:
The reactivity of various o-acylaniline derivatives with Ru complexes was examined The reaction of o-acylanilines with RuH2(CO)(PPh3)3 (1) or an activated Ru species formulated as Ru(CO)(PPh3)3 (4) gave amido hydrido complexes 3 and aryl amido complexes, e.g., I (R = H, Me, OMe, F, CF3), formed via N-H and C-N bond cleavage, resp. Addition of olefins, such as vinylsilanes, accelerates the C-N bond cleavage. The aryl amido complexes I can provide the C-N arylation product upon treatment with arylboronates. The relative reactivity of o-acylanilines bearing various substituents was studied by competition experiments, and electron-donating substituents increase the relative facileness of the C-N bond cleavage in both stoichiometric and catalytic reactions. The trend observed here is different from the one observed for the previously reported Ta-mediated C-N bond cleavage. The experimental process involved the reaction of tert-Butyl (4-(trifluoromethyl)phenyl)carbamate(cas: 141940-37-6).Formula: C12H14F3NO2
The Article related to aniline catalytic stoichiometric carbon nitrogen bond cleavage hydridoruthenium phosphine, pivaloylaniline cyclometalation ruthenium hydride complex, ruthenium pivaloylanilido complex preparation catalyst arylation acylaniline and other aspects.Formula: C12H14F3NO2
