Synthesis and characterization of a novel organic–inorganic hybrid salt and its application as a highly effectual Br?nsted–Lewis acidic catalyst for the production of N,N′-alkylidene bisamides

In this research, a novel organic–inorganic hybrid salt, namely, N1,N1,N2,N2-tetramethyl-N1,N2-bis(sulfo)ethane-1,2-diaminium tetrachloroferrate ([TMBSED][FeCl4]2) was

The synthesis and structure of pyridine-oxadiazole iridium complexes and catalytic applications: Non-coordinating-anion-tuned selective C–N bond formation

Several novel pyridine-oxadiazole iridium complexes were synthesized and characterized through X-ray crystallography. The designed iridium complexes revealed surprisingly high catalytic activity in C–N bondformation of amides and benzyl alcohols with the assistance of non-coordinating anions. In an attempt to achieve borrowing hydrogen reactions of amides with benzyl alcohols, N,N'-(phenylmethylene)dibenzamide products were unexpectedly isolated under non-coordinating anion conditions, whereas N-benzylbenzamide products were achieved in the absence of non-coordinating anions. The mechanism explorations excluded the possibility of “silver effect” (silver-assisted or bimetallic catalysis) and revealed that the reactivity of iridium catalyst was varied by non-coordinating anions. This work provided a convenient and useful methodology that allowed the iridium complex to be a chemoselective catalyst and demonstrated the first example of non-coordinating-anion-tuned selective C–N bond formation

N,N,N′,N′-tetramethylethylene-diaminium-N,N′-disulfonic acid trifluoroacetate and pyridinium-N-sulfonic acid hydrogen sulfate as highly effective dual-functional catalysts for the preparation of N,N′-alkylidene bisamides

In this research, Br?nsted-acidic ionic liquids N,N,N′,N′-tetramethylethylene-diaminium-N,N′-disulfonic acid trifluoroacetate ([TMEDSA][TFA]2) and pyridinium-N-sulfonic acid hydrogen sulfate ([Py-SO3H][HSO4]) have been introduced as dual-functional catalysts for the green, simple and effective preparation of N,N′-alkylidene bisamides by the reaction of primary amides (2 eq.) with arylaldehydes (1 eq.) under solvent-free conditions. The reaction results and conditions of the catalysts have been compared with the previously reported ones. [TMEDSA][TFA]2 and [Py-SO3H][HSO4] were superior to the previously reported catalysts in terms of two or more of these factors: Reaction times (10-45 min), yields (86-98%), temperature and the reaction conditions. Additionally, a plausible and attractive mechanism based on dual functionality of the catalysts has been proposed.

Synthesis, characterization and application of nano-N,N,N′,N′-tetramethyl-N-(silica-n-propyl)-N′-sulfo-ethane-1,2-diaminium chloride as a highly efficient catalyst for the preparation of N,N′-alkylidene bisamides

Abstract: A novel mesoporous nanomaterial, namely nano-N,N,N′,N′-tetramethyl-N-(silica-n-propyl)-N′-sulfo-ethane-1,2-diaminium chloride (nano-[TSPSED][Cl]2), was prepared, and characterized using Fourier-transform infrared spectroscopy (FT-IR), energy-dispersive X-ray spectroscopy (EDS), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), adsorption/desorption porosimetry (BET, Langmuir, BJH and adsorption/desorption isotherm), thermal gravimetric (TG), differential thermal gravimetric (DTG) and X-ray diffraction (XRD) analyses. Afterward, nano-[TSPSED][Cl]2 was used as a highly efficient and recyclable nanocatalyst for the condensation reaction of primary amides (2 eq.) with arylaldehydes (1 eq.) under solvent-free conditions to afford N,N′-alkylidene bisamides in high yields and in short times.
