	Abstract:An efficient ultrasonic irradiation promoted copper(I)-catalyzed azide-alkyne 1,3-dipolar cycloaddition was used for the synthesis of quinolinone derivatives linked with 1,2,3-triazole moiety. The efficiency of 1,3-dipolar cycloaddition were notably promoted through the introduction of ultrasound irradiation. A wide variety of applicable quinolinone derivatives containing 1,2,3-triazole unit were synthesized at room temperature in high yields and their structures were elucidated by 1H NMR, 13C NMR, IR and HRMS.

	Abstract:The N, N-dimethylamino-functionalized ionic liquid, (N, N-dimethylaminoethyl benzyldimethylammonium chloride) ([PhCH2Me2N+CH2CH2NMe2]Cl-), has been found to be an efficient catalyst for the Knoevenagel condensation. A wide range of aromatic aldehydes easily undergo condensations with ethyl cyanoacetate and malononitrile in water media and under solvent-free condition to afford the desired products of good purity in excellent yields. A recycling study confirmed that the catalyst could be used multiple times affording, with each run, the desired condensation product in excellent yields. Taking into account environmental and economical considerations, the protocol presented here has the merits of environmentally benign, simple operation, convenient work-up and good yields. Furthermore, the catalyst can easily be recovered and reused at least 5 times with comparable yields in water media.

	Abstract:In this study, a new kind of calcium-selective fluorescent probe Fluo-3ClMM-OH was synthesized. The structure of reaction products were characterized by IR and 1H NMR spectra. The molecular weights were measured on MALDI-TOF MS. Methylation of the crude product provided an effective method for separation. The fluorescence emission wavelength maxima of Fluo-3ClMM-OH were also researched.
