H-indol-3-yl)butanoic acid 4aaa was designed against BPH and synthesized by two steps of N-alkylation. One-pot protocol towards 4aaa was newly developed. With IL [C6min]Br as solvent, the yield of 4aaa was increased to 75.1 % from 16.0 % and the reaction time was shortened in 1.5 hours from 48 hours. 25 Derivatives structurally based on arylpiperazine and indolyl butyric acid with alkyl linker were

morpholino‐induced elimination of 5‐nitrobenzisoxazole into the relevant 2‐cyano‐4‐nitrophenolate has been used as a sample reaction in order to investigate molecular properties of some room temperature ionic liquids. The kinetic study was carried out at 298 K by means of spectrophotometric measurements. Ionic liquids, which differ in both their cation and anion properties, were used as solvent systems. In particular

Fifty-six ionicliquids were efficiently synthesized in parallel format under one-pot, solvent-freemicrowave-assisted synthesis. These compounds were evaluated as extracting agents of nitrogen-containing compounds from a real Diesel feed before being submitted to the hydrodesulfurization process to obtain ultralow sulfur Diesel. Our results showed that halogenated ionicliquids are an excellent alternative
This study examines the synthesis and properties of salts of the new tetrahedral [B(O–C2H4–CN)4]– anion, which can be synthesized by the reaction of tetrahedral NaBH4 and HO–C2H4–CN followed by salt metathesis. The structures of M[B(O–C2H4–CN)4] [M = Na, 1-ethyl-3-methylimidazolium (EMIm), 1-butyl-3-methylimidazolium (BMIm), 1-octyl-3-methylimidazolium (OMIm), Me4N, Et4N, and Bu4N] as well as the thermal
