Reactions of selenourea with benzoyl- and 2-thienoylbromoacetylenes: synthesis of 1,3-diselenetanes and 1,4-diselenafulvenes
摘要:
A novel reaction of selenourea with benzoylbromoacetylene and 2-thienoylbromoacetylene is described. The reaction proceeds in the presence of triethylamine at -30 to 0 degrees C to afford new 4- and 5-membered heterocycles. (c) 2007 Elsevier Ltd. All rights reserved.
