The 2,6‐diisopropylphenyl (Dipp) substituent is introduced to diaryl bismuth chemistry. Dipp2BiBr (1‐Br) was prepared by a Grignard reaction and subsequently used as precursor for synthesis of the other diaryl halido bismuthanes Dipp2BiX (1‐X, X=F, Cl, I) and the corresponding triflate Dipp2BiOTf (1‐OTf). Moreover, 1,1,2,2‐tetrakis(2,6‐diisopropylphenyl)dibismuthane (2) was prepared. All isolated compounds
的2,6-二异丙基苯基(迪普)取代基引入到二芳基铋化学。Dipp 2 BiBr (1-Br)通过格氏反应制备,随后用作合成其他二芳基卤代双变色烷Dipp 2 BiX(1-X,X = F,Cl,I)和相应的三氟甲磺酸盐Dipp 2 BiOTf的前体。 (1-OTf)。此外,1,1,2,2-四(2,6-二异丙丙基苯基)dibismuthane(2)已准备好。所有分离出的化合物均通过单晶X射线衍射分析,NMR光谱,IR光谱和元素分析进行表征。此外,向元素硫dibismuthane的反应性进行了研究,并且所形成的dibismuthanyl三-和五硫化二磷(3 一,3 b)进行表征单晶X-射线分析。用LiP t Bu 2或t Bu 2 PTMS(TMS = SiMe 3)对二芳基卤代双变色烷进行功能化可以使用interpnictogenogen化合物Dipp 2 Bi-P t Bu 2(4),
