An efficient and reusable heterogeneous catalyst with oxime-derived palladacycle immobilized in an ionic liquid brush has been synthesized and an environmentally-friendly procedure have been developed for coupling aryl iodides and bromides with acrylic acid. These reactions were conducted in neat water under aerobic conditions with water-insoluble or even solid aryl halides and they proceeded smoothly and cleanly without any organic co-solvent or other additives. The ionic liquid brush could be easily recovered and reused at least five times without significant loss of activity. The protocol has the advantages of excellent yields, environmental friendliness, and catalyst recyclability.

A fluorescent probe (2a-LP) based on an unnatural amino acid (UAA) is developed for the detection of phenylalanine ammonia lyase (PAL). In the presence of PAL, 2a-LP is catalytically deaminated to ortho-amino-transcinnamic acid (o-a-CA), which shows a rem

Phenyl-1,2,3-triazoles containing (E)-vinyl halide were readily synthesized via a one-pot, three-component reaction of 3-(4- or 2-azidophenyl)acrylic acid, NXS(X=Cl, Br and I) and 1-alkynes in MeCN-H2O (9:1v/v) catalyzed by LiOAc/CuI-sodium ascorbate syst
Facile synthesis of biologically active heterocycles by indium-induced reactions of aromatic nitro compounds in aqueous ethanol

Indium/ammonium chloride-induced reduction of aromatic nitro compounds to aromatic amines in aqueous ethanol was developed. Useful chemoselectivity was observed in the reduction reaction. This method was extended to reductive cyclization and rearrangement toward the synthesis of various biologically active heterocycles, including quinoline, oxazines, quinalonones, and phenanthridine in excellent yield. The oxophilicity of indium metal influenced the reaction in aqueous ethanol. Metals like zinc and tin were not effective in promoting this kind of reactions under the present environmentally friendly conditions.
