Abstract:A method for the conversion of diazonium salts into intrinsically
nucleophilic aryl indium reagents is described. The reaction is performed
using indium(I) bromide with the C–In bond being formed by
the interaction of aryl radicals with the indium salt. The obtained
aryl indium(III) reagents work well in the Liebeskind–Srogl
cross-coupling with thioesters, affording a wide variety of aryl ketones.
This two-step transformation is a general method for the acylation
of diazonium salts.
