Preparation of 2-Arylethynylselanylacetonitriles from 4-Aryl-1,2,3-selenadiazoles
O'Connor,Sachinvala,Ganjian
, p. 1167 - 1169 (2015/08/06)
Base decomposition of 4-(substituted phenyl)-1,2,3-selenadiazoles at room temperature resulted in 2-(substituted phenyl)-ethynylselenolate anions, which were immediately reacted with bromoacetonitrile to give a series of 2-(substituted phenyl)ethynylselan
