Phenacyl aryl sulfones as synthons for 1,2,3-selenadiazoles and thiadiazoles
Padmavathi, V.,Reddy, A. V. Bhaskar,Reddy, A. Somasekhar,Reddy, D. Bhaskar
, p. 1062 - 1065 (2007/10/03)
4-Aryl-5-arylsulfonyl-1,2,3-selenadiazole 4a-1 and 4-aryl-5-arylsulfonyl-1,2,3-thiadiazole 5a-1 have been prepared from phenacyl aryl sulfones (2a-1). The 4 on pyrolysis yields 1-arylsulfonyl-2-aryl acetylenes 6a-1.
