Twelve novel 7-diethylaminocoumarin-based 1,3,4-oxadiazole derivatives I [R = n-Bu, 2-thienyl, Ph, etc.] were synthesized via iodine-mediated oxidative cyclization and confirmed by 1H NMR, 13C NMR and HRMS. The synthesized derivatives I were tested against in-vitro acetylcholinesterase inhibitory activity and results showed that compounds I [R = 4-ClC6H4, 4-BrC6H4] exhibited moderate inhibitory activities with 69.19% and 65.06%, resp. The preliminary structure-activity relationships revealed that introduction of halogen atom on the para-position of Ph of compounds I could enhance their activities.

Four new palladium pincer complexes I (R = H, 3-OMe, 3-OEt, 5-Cl) incorporating ONO type furoylhydrazone ligands have been prepared in good yields. These palladium complexes were structurally characterized by elemental anal., IR, 1H- and 13C-NMR spectra. X-ray single crystal analyses of Pd1-Pd4 revealed that the metal center adopted a slightly distorted square planar geometry in which the hydrazone bound the metal ion via the phenolic-O, azomethine-N and imidolate-O atoms. Using these ONO pincer complexes as catalyst, excellent yields of biaryls could be obtained for coupling of arylboronic acids with aryl bromides at a low catalyst loading (0.01 mol%).

Furan Schiff base functionalized PEG (PEGFB) was synthesized as an excellent reversible fluorescent chemosensor for the sensitive detection of Al3+ in 100% aqueous solution The non-fluorescent PEGFB displayed high selectivity towards Al3+ over other coexistent metal ions, accompanied by a visual fluorescence change from colorless to bright cyan. The detection limit of PEGFB towards Al3+ was determined to be 7.90 x 10-9 M. PEGFB could be utilized to detect Al3+ in a relatively wide pH range from 5 to 9. The reversible fluorescence response of PEGFB upon the addition of Al3+ and EDTA was successfully used to construct an INHIBIT mol. logic gate.
