Abstract
Cyclodehydration of various α-aryloxy ketones proceeded
to give various multisubstituted benzofurans by using an Ir(III) catalyst,
which was prepared from [Cp*IrCl2 ]2 ,
AgSbF6 , and Cu(OAc)2 . The use of the cationic
iridium complex with a carboxylate salt realized the efficient transformation
at ambient temperature.
Key words
C-H activation - benzofurans - cyclodehydration - iridium - room temperature

12 Other silver salts, such as AgOTf
and AgBF4 , gave poorer results than AgSbF6 .
13 Iridium dicarboxylate complex, which
was prepared from [Cp*IrCl2 ]2 (5
mol% Ir), AgSbF6 (10 mol%), and KOPiv
(10 mol%), had almost no catalytic activity.
