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.
