, p. 37 - 42 (2013)
A new fluorescent chemosensor based upon 2,5-diphenylfuran and 8-hydroxyquinoline was designed and synthesized. Its structure was confirmed by single crystal X-ray diffraction and its photophysical properties were studied by absorption and fluorescence spectra. This compound can be used to determine Fe3+ ion with high selectivity among a series of cations in aqueous DMF. This sensor forms a 1:1 complex with Fe3+ and displays fluorescent quenching.

A new fluorescent chemosensor based upon 2,5-diphenylfuran and di(2-picolyl)amine (DPA) was designed and synthesized. Its structure was confirmed by single crystal X-ray diffraction and its photophysical properties were studied by absorption and fluorescence spectra. This compound can be used to determine Cu2+ ion with high selectivity among a series of cations in aqueous DMSO. This sensor forms a 1:1 complex with Cu2+ and displays fluorescent quenching.

The copper(II) trifluoromethanesulfonate-catalyzed Pummerer reaction of β-ketosulfoxides with 1,3-dicarbonyl compounds or π-nucleophiles such as phenols, arenes, and tetraallylsilane is reported. The mild conditions provide an efficient entry to a novel class of polysubstituted 3-alkylthiofuran and polysubstituted 3-thiobenzofuran heterocycles from readily available materials.

(Chemical Equation Presented) 2-(Methylthio)-1,4-diaryl-2-butene-1,4-dione (3) are prepared from readily available aryl methyl ketones in the presence of copper(II) oxide, iodine, and dimethyl sulfoxide. The success of the cross-coupling reaction of 4-chloroacetophenone with 2-acetylthiophene confirms a proposed self-sorting tandem reaction mechanism. Both Z- and E-isomers of compound 3 are readily converted into the corresponding 3-methylthio 2,5-diaryl furan 7 in good yield through a domino process involving the reduction of the double bond followed by the Paal-Knorr furan synthesis. Meanwhile, 4-bromo-3-methylthio 2,5-diaryl furan 10 is obtained either by the treatment of furan 7 with molecular bromine or by the treatment of diketone 3 with 30% hydrogen bromide in acetic acid solution in one pot. Removal of the methylthio group is accomplished by the treatment of 7 with Raney Ni in ethanol, which affords the diaryl-substituted furan 11 in excellent isolated yield. Selective reduction of the double bond of compound 3 leads to the formation of the saturated 1,4-diketone 13, which is easily converted to the corresponding 3-methylthio-2,5-diaryl-substituted pyrrole 14 and thiophene 15 via the Paal-Knorr cyclization reaction.
