Indium compounds, aryl halide reactions with

Highly regioselective radical addition of the indium hydride reagent HInCl2 to alkynes has been achieved. Various functionalities are tolerant under the reaction conditions. The reaction proceeds with complete // -stereoselectivity. Alkenylindium compounds obtained by this hydroindation can be employed for the subsequent cross-coupling reactions with aryl halides in one pot (Scheme 109).374,375... 

Only two methods for the preparation of phenylindium halides have been reported (i) transmetallation of Grignard reagents with indium trihalides [10] and (ii) the reaction of triphenylindium with Br2 or I2 [11]. No work had appeared in the literature concerning the direct preparation of diphenylindium halides from indium metal and aryl halides. The only related work reported was the preparation of pentafluorophenylindium compounds from indium...
