Coordination polymers with free Bronsted acid sites for selective catalysis

By employing the 5-nitro-1,2,3-benzenetricarboxylate ligand, two Cu(ii) coordination polymers with free -COOH groups as Bronsted acid sites are synthesized, and both compounds show high activity and regioselectivity in catalyzing epoxide ring-opening reac

Solvent-free aminolysis of aliphatic and aryloxy epoxides with sulfated zirconia as solid acid catalyst

Single-step and two-steps synthetic procedure for the synthesis of sulfated zirconia (SZ) was developed, which were calcined at 500, 600 and 700 °C and characterized by various physico-chemical methods such as PXRD, FTIR, surface area, microanalysis, NH3-TPD and DRIFT analysis. These SZ materials were then employed as solid acid catalysts for the aminolysis of different aliphatic/aromatic terminal, aryloxy and meso epoxides with aromatic and aliphatic amines under ambient conditions. Amongst the catalyst prepared, SZ-2-600 prepared in two-steps and 600 ° C calcined was found to be the most efficient catalyst to give p-amino alcohols in up to 98% yield and 7gt;99% regioselectivity. The SZ catalyst was successfully recycled and reused up to six catalytic runs with intact efficiency.

N-Fluorobenzenaminium tetrafluoroborate generated in situ by aniline and Selectfluor as a reusable catalyst for the ring opening of epoxides with amines under microwave irradiation

The ring opening of epoxides with aromatic and aliphatic amines was carried out under solvent free conditions using N-fluorobenzenaminium tetrafluoroborate (2 mol%) generated in situ by the reaction of aniline and Selectfluor as a catalyst with microwave irradiation. Excellent yields of β-amino alcohols were obtained. The catalyst also results in the retention of the stereochemistry for the ring opening of enantiopure epoxide with amine. The catalyst was recovered and reused up to 4 cycles for the ring opening of cyclohexene oxide with aniline. This journal is

2D Naphthalenedisulfonate-cadmiun coordination polymer with 2,4,5-tri(4-pyridyl)-imidazole as a co-ligand: Structure and catalytic property

A new 2D coordination polymer, [Cd(tpim)(1,5-nds)]n (1), was constructed from 1,5-naphthalenedisulfonate (1,5-nds), 2,4,5-tri(4-pyridyl)- imidazole (tpim) and Cd(CH3COO)2·2H2O, which can be subsequently used to

Three-dimensional {Co3+-Zn2+} and {Co 3+-Cd2+} networks originated from carboxylate-rich building blocks: Syntheses, structures, and heterogeneous catalysis

The present work shows the utilization of Co3+ complexes appended with either para- or meta-arylcarboxylic acid groups as the molecular building blocks for the construction of three-dimensional {Co 3+-Zn2+} and {Co3+-Cd2+} heterobimetallic networks. The structural characterizations of these networks show several interesting features including well-defined pores and channels. These networks function as heterogeneous and reusable catalysts for the regio- and stereoselective ring-opening reactions of various epoxides and size-selective cyanation reactions of assorted aldehydes.

Efficient solvent-free aminolysis of epoxides under (C4H 12N2)2[BiCl6]Cl·H 2O catalysis

An efficient and rapid procedure for ring opening of various epoxides with aromatic, aliphatic and heterocyclic amines is developed at room temperature under solvent-free conditions in the presence of (C4H 12N2)2[BiCl6]Cl·H 2O (1 mol %). This catalyst can be reused several times without losing of its activity.

Enantioselective desymmetrization of meso-epoxides with anilines catalyzed by polymeric and monomeric Ti(IV) salen complexes

The active catalysts for the enantioselective ring opening (ARO) of meso-stilbene oxide, cis-butene oxide, cyclohexene oxide, cyclopentene oxide, and cyclooctene oxide with various substituted anilines were generated in situ by the reaction of Ti(Oi

We report the synthesis and structural characterization of two-dimensional {Co3+-Zn2+} and {Co3+-Cd2+} heterobimetallic networks and their catalytic applications in heterogeneous and solvent-free ring opening reactions of various epoxides. The Royal Society of Chemistry.

Hβ zeolite: An efficient and reusable catalyst for ring-opening of epoxides with amines under microwave irradiation

A solvent-free protocol for the synthesis of β-amino alcohols (Yield, up to 94%) is demonstrated by the ring-opening reactions of meso and terminal epoxides with aromatic amines using Hβ zeolite as catalyst under microwave irradiation. The catalytic syste

Aminolysis of epoxides using iridium trichloride as an efficient catalyst

Iridium trichloride catalyzes the ring opening of epoxides by aryl, heterocyclic, or aliphatic amines under mild conditions. The reactions proceed at room temperature to afford the corresponding b-amino alcohols in excellent yields. In general, the aminolysis of cyclopentene oxide is faster than that of cyclohexene oxide in the presence of iridium trichloride as a catalyst. Georg Thieme Verlag Stuttgart.
