R f I (R f = C 2 F 5 , n‐C 3 F 7 , n‐C 4 F 9 , n‐C 6 F 13 , i‐C 3 F 7 , C 6 F 5 ) and In(C 2 H 5 ) 3 react in a variety of solvents with formation of the derivatives In(C 2 H 5 ) 2 R f as the major products. However, strong bases like N(C 2 H 5 ) 3 are required to stabilize the compounds. In(C 2 H 5 ) 2 (C 6 F 5 ) · N(C 2 H 5 ) 3 and In(C 2 H 5 ) 2 (i‐C 3 F 7 ) · N(C 2 H 5 ) 3 were isolated from the reactions in the presence of N(C 2 H 5 ) 3 as NMR spectroscopically pure oily liquids in moderate yields (64% and 40%). With exception of C 2 F 5 I all perfluoroiodo‐n‐alkanes reacted with In(C 2 H 5 ) 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(C 2 H 5 ) 3 , C 2 F 5 I reacted with In(C 2 H 5 ) 3 with formation of In(C 2 H 5 )(C 2 F 5 )I · N(C 2 H 5 ) 3 as the major product, in the absence of N(C 2 H 5 ) 3 mainly In(CH 2 CH 2 CF 2 CF 3 ) 2 I was formed. All reactions described have in common that In(C 2 H 5 ) 2 F 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 R f H as the only fluorine containing compound.
