On the chemistry of fluoroorgano derivatives of group 13 elements. 1 The reactions of perfluoroiodoalkanes and pentafluoroiodobenzene with triethylindium - Synthesis and characterization of In(C2H5)2(C6F5) · N(C2H5)3 and In(C2H5)2(i-C3F7

RfI (Rf = C2F5, n-C3F7, n-C4F9, n-C6F13, i-C3F7, C6F5) and In(C2H5)3 react in a variety of solvents with formation of the derivatives In(C2H5)2Rf as the major products. However, strong bases like N(C2H5)3 are required to stabilize the compounds. In(C2H5)2(C6F5) · N(C2H5)3 and In(C2H5)2(i-C3F7) · N(C2H5)3 were isolated from the reactions in the presence of N(C2H5)3 as NMR spectroscopically pure oily liquids in moderate yields (64% and 40%). With exception of C2F5I all perfluoroiodo-n-alkanes reacted with In(C2H5)3 to give the corresponding products, which contained impurities up to 25% that could not be separated by common methods. In the presence of N(C2H5)3, C2F5I reacted with In(C2H5)3 with formation of In(C2H5)(C2F5)I · N(C2H5)3 as the major product, in the absence of N(C2H5)3 mainly In(CH2CH2CF2CF3)2I was formed. All reactions described have in common that In(C2H5)2F precipitated from the reaction mixtures irrespective of the iodo component. All derivatives can be stored for several months at temperatures below -25°C, at ambient temperature they decompose within a few days giving RfH as the only fluorine containing compound.
