Organoindium compounds. I. Preparative routes to pentafluorophenylindium compounds

Abstract

Trispentafluorophenylindium has been prepared by heating iodopentafluoro-benzene with an excess of indium metal, but was obtained mixed with iodobispenta-fluorophenylindium when the stoicheiometric amount was used. An attempted synthesis by thermal decomposition of indium trispentafluorobenzoate was un-successful. Reaction of indium with bispentafluorophenylmercury and subsequent treatment with ether gave (C6F5)3In,OEt2. The complex (C6F5)3In,diox (diox = 1,4-dioxan) has been obtained by reaction of indium trichloride with pentafluorophenyl-magnesium chloride or with an excess of bispentafluorophenylmagnesium, and C6F5InCl2,diox from bispentafluorophenylmagnesium and an excess of indium trichloride.
