A convenient and effective protocol for the ruthenium-catalyzed C–H selenylations of benzamide was achieved under mild reaction conditions. The robust ruthenium catalyst tolerated a wide range of functional groups and set the stage for the preparation for diversely decorated benzamides. The amide directing group could be transferred to carboxylic acid, aldehyde and tetrazoles. Preliminary mechanistic study indicated a base-assisted electrophilic-type substitution C–H activation event.

We present the synthesis, spectroscopic properties, and live-cell application of a new BODIPY (boron dipyrromethene) fluorescence probe BOD-Se based on selenoxide spirocyclization reaction for peroxynitrite detection. The probe employs BODIPY dye as fluorophore, and is integrated with a chemical peroxynitrite responsive organoselenium functional group. By using reactive diaryl selenide and modulating by intramolecular charge-transfer (ICT) process, the probe is employed for evaluating intracellular peroxynitrite level changes. Different intracellular peroxynitrite levels can be detected with BOD-Se by confocal microscopy experiments using mouse macrophage cell line RAW264.7.
Copper nano-catalyst: Sustainable phenyl-selenylation of aryl iodides and vinyl bromides in water under ligand free conditions

experimental part, p. 1652 - 1657 (2009/06/28)
A simple and efficient procedure for the synthesis of aryl- and vinyl-selenides has been developed by a copper nanoparticle catalysed reaction of aryl iodide/vinyl bromide with diphenyl diselenide in the presence of zinc in water. (E)-Vinyl bromides produce (E)-vinyl selenides stereoselectively, whereas (Z)-vinyl bromides provide mixtures of (E) and (Z) isomers. The catalyst was recycled.
Syntheses and reactions of cyclic Se-alkoxy-Se-chloroselenuranes and alkoxyselenonium salts
Kataoka, Tadashi
, p. 317 - 326 (2007/10/03)
Several 1-chloro-2,1-oxaselenole selenuranes 3a-e and selenonium salts 4a-c and 5-chloro-5,11-epoxy-6,11-dihydrodibenzo[b,e]selenepines 12a and 12b and selenonium salts 13a-c-were synthesized, and their reactions with organometallic reagents were studied.
