Tanaskov, M. M.,Starodub, P. E.,Stadnichuk, M. L.,Tanaskova, E. A.

, p. 1609 - 1615 (2007/10/02)

At room temperature arylsulfonyl thiocyanates add to conjugated dienes with the formation of 1,4-addition products.In all cases the organic sulfonyl radical is fixed at the least substituted carbon atom of the 1,3-diene system.In reaction with triethylamine or sodium ethoxide the adducts which form eliminate thiocyanic acid with the formation of conjugated dienyl sulfones.
