Highly ordered Prussian blue nanowire arrays with diameters of about 50 nm and lengths up to 4µm have been fabricated for the first time by an electrodepositing technology with two-step anodizing anodic aluminum oxide films. X-ray diffraction and transmission electron microscopy measurement results show that the Prussian blue nanowires are dense, continuous, and highly crystalline with an fcc cubic structure of a ) 10.14 Å. The Mo 1ssbauer spectrum and infrared spectrum at room temperature indicate that the nanowires are ferric ferrocyanide: one kind of iron is Fe 3+ with high spin and the other is Fe 2+ with low spin. Magnetic property measurement results indicate that the Curie temperature of Prussian blue nanowire decreases as the average numbers of magnetic interaction neighbors is reduced.

A straightforward N-trifluoroethylation of anilines has been developed based on silver-catalyzed N-H insertions with 2,2,2-trifluorodiazoethane (CF3CHN2). Mechanistically, the reaction is proposed to involve migratory insertion of a silver carbene as the key step. In contrast, when amides are employed as the substrates under similar reaction conditions, O-trifluoroethylation occurs to afford trifluoroethyl imidates.

A novel and efficient methodology that allows for the construction of Ar-P bonds via the Pd-catalyzed oxidative cross-coupling reaction of various arylsilanes with H-phosphonates leading to valuable arylphosphonates has been developed.
