A new method has been developed for the copper(I)-mediated trifluoromethylthiolation of α-bromoketone using commercial anhydrous potassium fluoride, elemental sulfur, and (trifluoromethyl)-trimethylsilane in anhydrous N,N-dimethylformamide. This protocol provides facile access to a variety of α-trifluoromethylthiolated carbonyl compounds in moderate to excellent yields under mild and ligand free conditions

A new method for the preparation of α-bromoketones from olefins using bromide/bromate couple as a nonhazardous brominating agent has been developed. Several α-bromoketones were successfully prepared from a variety of olefins by this method. This procedure is an alternative to conventional molecular bromine.

The synthesis, characterization, and photophysics of a series of solution-processable and strongly visible-light absorbing platinum(II) polyynes containing bithiazole-oligo(thienyl) rings were presented. Tuning the polymer solar cell efficiency, as well as optical and charge transport properties, in soluble, low-band gap PtII-based conjugated poly(heteroaryleneethynylene)s using the number of oligothienyl

A second-generationlibrary of 2-aminoimidazole-based derivatives incorporating a "reversed amide" (RA) motif in comparison to the marine natural product oroidin were synthesized and subsequently assayed for antibiofilmactivity against the medically relevant Gram-negative proteobacteria P. aeruginosa and A. baumannii. Most notably, an in-depth activity profile is reported for the most active subclass
