Activation of Nitrous Oxide by Dinuclear Ruthenium Complexes

Rosario Scopelliti, Kay Severin, Euro Solari, Alexander Tskhovrebov

The dinuclear Ru(II) complexes (arene)Ru(μ-Cl)3RuCl(C2H4)(PCy3) (arene = p-cymene or 1,3,5-C6H3iPr3) react with N2O under mild conditions to give OPCy3 and the trinuclear complexes (arene)Ru(μ-Cl)3Ru(μ-Cl)3Ru(arene). The N-heterocyclic carbene complex (p-c ...

Selective three-phase hydrogenation of aromatic nitro-compounds over β-molybdenum nitride

Lioubov Kiwi, Fernando Cardenas Lizana, Daniel André Samuel Lamey

A tetragonal molybdenum nitride (β-Mo2N) has been prepared by temperature programmed treatment of MoO3 in flowing N2 + H2 and for the first time shown to catalyze the liquid phase selective hydrogenation (T = 423 K; PH2=11bar) of a series of para-substitut ...

Enantioselective Rhodium(I)-Catalyzed [3+2] Annulations of Aromatic Ketimines Induced by Directed C?H Activations

Nicolai Cramer, Duc Tran Ngoc

Triple selectivity: Highly substituted indenylamines can be obtained with high enantioselectivity by formal [3+2] additions of aryl ketimines with internal alkynes. These rhodium(I)-catalyzed processes proceed by selective C-H activation of one of the two ...
