: An efficient and facial one-pot synthesis of 4-aryl-3,4-dihydrobenzo[g]quinoline- 2,5,10(1H)-triones was developed for the first time. The process proceeded via the three-component cyclocondensation of 2-amino-1,4-naphthoquinone with Meldrum’s acid and substituted benzaldehydes under green conditions. The fused 3,4-dihydropyridin-2(1H)- one-ring naphthoquinones have been synthesized with good to high yields in refluxing ethanol as a green reaction medium. This protocol is simple and effective as well as does not involve the assistance of the catalyst, additive, or hazardous solvents.

A high-yielding cyclocondensation of 4-hydroxycoumarin, phenylglyoxal monohydrate, and heteroarylamines proceeds without catalysis, which gives novel functionalized furo[3,2-c]coumarins and heteroarylamino alkylation of coumarin products in acetonitrile under reflux, is reported for the first time. This tandem process involves sequentially an aldol condensation, Michael addition, a ring closure, and dehydration reaction.

Some hitherto unreported thiazolo[3,4- a]quinoxaline derivatives have been synthesised in excellent yields via a one-pot, three-component reaction of benzene-1,2-diamines, ethyl bromopyruvate and aryl isothiocyanates in MeCN, for the first time. The protocol avoids the use of any catalysts or chromatographic separations and provides a wide range of novel thiazolo[3,4- a]quinoxalines.

The rate-accelerating effects of fluoroalcohol solvents for generating trivalent hypervalent iodine species and the conversion into diaryliodonium(iii) salts have been used for the first time to realize a facile and clean one-pot synthesis of diaryliodonium(iii) salts 3 from aryl iodides 1 and suitable arene partners 2 with peracetic acid (PAA). The use of PAA as a green and practical oxidant is significantly effective in fluoroalcohol solvents. The scope and limitations of the methodology are elucidated by investigation of a wide variety of representative substrates.

First Time

One-pot synthesis of polyaniline/Fe3O4 nanocomposite in 1-methyl-3-alkylcarboxylic acid imidazolium chloride ([CMMIm]Cl) ionic liquid (IL) was introduced for the first time in this work. Transmission electron microscopy (TEM), X-ray diffraction (XRD), four probes method and vibrating sample magnetometer (VSM) were used to explore the influence of IL on the structure, conductivity and magnetic properties of polyaniline/Fe3O4 composite. Compared with Fe3O4 particles prepared in water, the results show that Fe3O4 particles prepare in imidazolium-based ionic liquid were more regular in shape and dispersed uniformly. So the Fe3O4 nanoparticles prepared in IL can easier serve as cores to form the polyaniline/Fe3O4 nanocomposite via in situ chemical oxidative polymerization of aniline molecule. The saturation magnetization of polyaniline/Fe3O4 nanocomposite prepared in ionic liquid shows about 2 times higher than polyaniline/Fe3O4 composite prepared in water. And the conductivities of PANI/Fe3O4 composite prepared in IL decreased and the saturated magnetization increased with the increasing amount of Fe3O4.
