Va. Potapov et al., FIRST STEREOSPECIFIC SYNTHESIS OF (E)-1,2-BIS(SELENOCYANATO)ETHENES BY THE ADDITION OF DICYANODISELENIDE TO ACETYLENES, Recueil des travaux chimiques des Pays-Bas, 115(10), 1996, pp. 443-443
The addition of dicyanodiselenide to acetylene, phenylacetylene and di
phenylacetylene proceeds in an anti manner to afford, in 70-80% yield,
(E)-1,2-bis(selenocyanato)ethenes which are prospective precursors of
polymers with potential conductivity.
