2,6‐Diisopropylphenyl substituted Bismuth Halide and Interpnictogen Compounds

Abstract

AbstractHerein, we report about the preparation of several new 2,6‐diisopropylphenyl (Dipp) substituted (halido‐) bismuthanes, namely, Dipp3Bi (1) and compounds of the form DippBiX2(X=Cl, Br, I;2–4). The compounds2–4show a variety of structural motifs in their solid state structures. Reactivity of2towards the nucleophiles LiNMe2and MeLi was examined, where mostly scrambling reactions with a preference for two Dipp substituents at bismuth were observed. Therefore, the compounds Dipp2BiNMe2(5) and Dipp2BiMe (6) are the main products of these reactions. Moreover, new interpnictogen compounds with Bi−N, ‐P, and ‐Sb single bonds were prepared. Compound5was successfully used as precursor for the preparation of Dipp2BiNHtBu (7) and Dipp2BiSbMes2(8), one of very few isolated compounds with a Bi‐Sb single bond. Moreover, bismuthanyl phosphanes bearing functional groups (Dipp2BiPtBu(SiMe3) (9), Dipp2BiPHtBu (10)) have been prepared. Compound10is the first isolated secondary phosphane with a bismuthanyl substituent. All isolated compounds were analyzed via IR and NMR spectroscopy, mass spectrometry, elemental analysis and single crystal X ray diffraction.
