Nanoscopic hybrid systems with a polarity-controlled gate-like scaffolding for the colorimetric signalling of long-chain carboxylates.

Hybrid mesoporous systems containing a gate-like ensemble functionalised with imidazolium groups and a dye are used for the selective colorimetric sensing of long-chain carboxylates.

A "by-productless" cellulose foaming agent for use in imidazolium ionic liquids.

Cellulose foams, or sponges, are produced from solutions in ionic liquids by the aqueous acid mediated decomposition of 1-alkyl-3-methylimidazolium-2-carboxylates, where the alkyl group and acid may be selected such that the by-product is the ionic liquid solvent: a by-productless foaming.

STRUCTURAL EVALUATION OF THE ENZYMATIC RESOLUTION OF TRICYCLO[5.2.1.02,6]DECENE-2-CARBOXYLATES USING PIG’S LIVER ESTERASE

Moderate to excellent entantio- and stereoselectivities (ee’s 54-100%) were observed in PLE catalyzed hydrolysis of (±)-ethyl 5-oxo-endo-tricyclo[5.2.1.02,6] deca-8-ene-2-carboxylate 5 and the structurally related open chain bicyclic structures (±)-ethyl 3-acetylbicyclo[2.2.1]hept-5-ene-2-carboxylates 7, 9 and (±)-ethyl 3-propanoylbicyclo[2.2.1]hept-5-ene-2-carboxylates 8, 10.

Fe(II)/Et3N-Relay-catalyzed domino reaction of isoxazoles with imidazolium salts in the synthesis of methyl 4-imidazolylpyrrole-2-carboxylates, its ylide and betaine derivatives

A simple approach was developed for the synthesis of methyl 4-imidazolylpyrrole-2-carboxylates from easily available compounds, 5-methoxyisoxazoles and phenacylimidazolium salts under hybrid Fe(II)/Et3N relay catalysis. The products were easily transformed into the corresponding 3-(5-methoxycarbonyl-1H-imidazol-3-ium-3-yl)pyrrol-1-ides, which in turn can be hydrolyzed under basic conditions int...

Palladium-catalyzed multicomponent synthesis of 2-imidazolines from imines and acid chlorides.

We describe the palladium-catalyzed multicomponent synthesis of 2-imidazolines. This reaction proceeds via the coupling of imines, acid chlorides and carbon monoxide to form imidazolinium carboxylates, followed by a decarboxylation. Decarboxylation in CHCl(3) is found to result in a mixture of imidazolinium and imidazolium salts. However, the addition of benzoic acid suppresses aromatization, a...
