A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 29968-78-3, Name is 4-Nitrophenylethylamine hydrochloride, molecular formula is C8H11ClN2O2. In an article, author is Dhara, Dipankar,once mentioned of 29968-78-3, Computed Properties of C8H11ClN2O2.
Sequential activation of a-bonds : Intermolecular cascade annulation with migration and remote functionalization
We demonstrate a new catalytic property of the lanthanide compound CeCl3 center dot 7H(2)O which sequentially activates N-H, sp(2) C-H and sp(3) C-H sigma-bonds at ambient temperature. The powerful catalyst enables selective C-C and C-N bond-forming intermolecular cascade annulation between enamines and diary1-1,2-diketone to afford functionalized 3,3-diaryl-3-pyrrolin-2-ones involving migration of an aromatic ring. We have also initiated a new multicomponent strategy utilizing readily available and inexpensive precursors and environmentally benign CeCl3 center dot 7H(2)O as an efficient catalyst under benign reaction conditions towards direct synthesis of several N-heterocycles including pentasubstituted 2-pyrrolinones and pyrroles. These observations provide new prospects and perspectives in sigma-bond activation process for easy access to functional molecules.
