“…When the selenocyanate 3 was treated with the lithium salt of trimethylsilylacetylene (TMSA), compound 9 was obtained in 34 % yield. The trimethylsilyl group of 9 was removed with a 0.1  solution of NaOH in methanol [19] to give the ethynyl selenide 2 in 76 % yield.…”

Keywords: van der Waals interactions / NMR spectroscopy / Selenium / Hydrogen bonds / Density functional calculationsTo investigate the intramolecular van der Waals interactions between two divalent selenium centers in the solid state and in solution, we have prepared methyl 2-(methylselenyl)benzyl selenide (1), ethynyl 2-(methylselenyl)benzyl selenide (2), and 2-(methylselenyl)benzyl selenocyanate (3). By means of NMR spectroscopic studies we have determined the 77 Se NMR chemical shifts of the signals of the Se centers of 1-3 and their long-range 4 J Se,Se coupling constants. These results, and the X-ray structural studies of single crystals of 3 and 11, a quasi-dimer of 2, point to an Se···Se van der Waals
