MeTe R f ( R f = CF 3 , C 2 F 5 ) can easily be prepared via the reactions of methyl iodide and the corresponding tetramethylammonium perfluoroalkyltellurates(0), [NMe 4 ]Te R f ( R f = CF 3 , C 2 F 5 ). Both compounds are easily oxidized by xenon difluoride and the heavier halogens to yield the corresponding dihalides, MeTe( R f ) X 2 ( X = F, Cl, Br, I) and by ArI(OCOCF 3 ) 2 to give the corresponding trifluoroacetates, MeTe( R f )(OCOCF 3 ) 2 . All compounds are characterized byspectroscopic means. The molecular structures of MeTe( R f )F 2 ,MeTe( R f )Cl 2 , MeTe( R f )Br 2 , and of 4‐MeC 6 H 4 I(OCOCF 3 ) 2 were elucidated by XRD methods.
