On the chemistry of fluoroorgano derivatives of group 13 elements. 1 - Thereactions of perfluoroiodoalkanes and pentafluoroiodobenzene with triethylindium - Synthesis and characterization of In(C2H5)(2)(C6F5)center dot N(C2H5)(3) and In(C2H5)(2)(i-C3F7)center dot N(C2H5)(3) and spectroscopic evidence for bis(3,3,4,4,4-pentafluorobutyl)indium iodide

RfI (R-f=C2F5, n-C3F7, n-C4F9, n-C6F13, i-C3F7, C6F5) and Zn(C2H5)(3) react in a variety of solvents with formation of the derivatives In(C2H5)(2)R-f as the major products. However, strong bases like N(C2H5)(3) are required t o 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(C2H 5)3 as NMR spectroscopically pure oily liquids in moderate yields (64% and 40%). With exception of C2F5I all perfluoroiodo-n-alkanes reacted with In(C 2H5)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(C2H 5)(3), C2F5I reacted with In(C2H5)3 with formation of In(C2H5)(C2F5)I . N(C 2H5)3 as the major product, in the absence of N(C2H5)3 mainly In(CH2CH2CF2C F3)(2)I was formed. All reactions described have in common that In(C2H5)(2) F precipitated from the reaction mixtures irrespective of the iodo componen t. All derivatives can be stored for several months at temperatures below - 25 degrees C; at ambient temperature they decompose within a few days givin g RP as the only fluorine containing compound.
