With chlorine and bromide, diselenide lb provides quantitative yields of monomeric selenenyl halides i-Pr3C6H2SeCl [δ(77Se) 926.1 ppm] and i-Pr3C6H2SeBr [δ(77Se) 757.7 ppm; Me2Se standard and C6D6 solvent in all cases; spectra recorded at 54.24 MHz on a Bruker AM 300 instrument). Both compounds were isolated in a pure state: Martens, A. Diplomarbeit, University of Oldenburg, 1988.
