Perfluoroalkylbismuth Compounds. I. Mixed Alkylperfluoroalkyl Derivatives

Abstract

Perfluoroalkyl iodides react directly with trialkylbismuth compounds at 100�C to form dialkylperfluoroalkyl- and alkylbisperfluoroalkylbismuthines. These previously unknown compounds decompose below their boiling points. They are readily oxidized and may be hydrolysed by aqueous alkali, liberating the appropriate fluorocarbon. Halogens rapidly split off both alkyl and perfluoroalkyl groups. Whereas interconversion of the mixed alkylperfluoroalkyl compounds readily occurs, attempts to form the fully perfluoroalkylated bismuth compounds have been unsuccessful. Vapour pressure-temperature and infrared spectral data are presented and discussed.

Pentafluoroethyl Bismuth Compounds

“…Mixed alkyl perfluoroalkyl bismuthanes were first synthesized by Bell, Pullman and West in 1963 by the dismutation reaction of Bi(CH 3 ) 3 and CF 3 I . The tertiary Bi(CF 3 ) 3 was produced by Lagow et al.…”

“…Examples for successful alkyl-perfluoroalkyl group exchange reactions in main group chemistry are e. g. those of Te(CH 3 ) 2 and R f I to yield Te(CH 3 )R f [6] and of Bi(CH 3 ) 3 and CF 3 I giving mixtures of Bi(CH 3 ) 2 (CF 3 ) and Bi(CH 3 )(CF 3 ) 2 [7].…”

Preparation, Thermal Behaviour, and Structure of Calcium Trifluoroacetate Monohydrate

“…Swarts [1] has ®rst reported data on the synthesis and some properties of the tri¯uoroacetates of Cu, Ag, Hg, Ba, and Pb. More recently, such data have been published on the salts of the tri¯uoroacetic acid with alkali metals [2±4], metals of groups IIA [3, 5±7], IVA and IVB [8,9], VIA [10,11], and VIIIA [6,10,12,13] as well as with yttrium, lanthanum and some lanthanides [14±18], manganese [10], zinc [6,10], aluminum [5], and bismuth [19].…”
