Direct aromatization of chlorohydroazulenones with triflic anhydride: access to chloroazulenyl triflates
摘要:
A direct and efficient aromatization of chlorohydroazulenones has been achieved by using triflic anhydride and then lutidine or tropylium cation to afford selectively chloroazulenes and chloroazulenyl triflates, respectively. (C) 2008 Elsevier Ltd. All rights reserved.
