  摘要：

  The stable 1,2-dibromodialumane(4) Bbp(Br)Al-Al(Br)Bbp (1; Bbp = 2,6-bis[bis(trimethylsily)methyl]phenyl) was synthesized by the reduction of the corresponding dibromoalumane etherate BbpAlBr(2)center dot OEt2 (2). The structure and properties of 1 have been elucidated on the basis of the analyses of spectroscopic and crystallographic data and are supported by DFT calculations.

  hydrogen and halogen substituents (RHP–AlXR, R = organic substituent, X = halogen) are expected to be useful synthetic precursors for P=Al doubly bonded species, phosphaalumenes (RP=AlR), though there have been only limited number of H,X‐functionalized phosphanylalumanes. In this communication, synthesis and structure of a Lewis base coordinated phosphanylalumane bearing P–H and Al–Br moieties are

  带有氢和卤素取代基（RHP–AlXR，R =有机取代基，X =卤素）的膦酰基铝化合物有望成为P = Al双键物种phosphalalumenes（RP = AlR）的有用合成前体。H，X官能化的磷酰基铝铝烷。在这种交流中，报道了带有PH和Al-Br部分的路易斯碱配位的膦酰基铝铝烷的合成和结构。LiPHMes与BbpAlBr 2（OEt 2）Bbp = 2,6- [CH（SiMe 3）2 ] 2 C 6 H 3 }的反应，然后用N-杂环卡宾（L）处理，得到配位的Lewis碱H，Br官能化的磷腈铝硼烷MesP（H）-Al（Br）（L）Bbp（L = N-杂环卡宾）。它的Al-P键长度与先前报道的没有Lewis碱配位的H，Cl官能化的磷酰铝硼烷的观察到的相当，表明Al = P双键特性在磷酰铝硼烷衍生物中的贡献可忽略不计。
