  • Versatile Approach to 3-Phosphahexatrienes Bearing Low Coordinated Phosphorus
    作者:Anna I. Arkhypchuk、Yurii V. Svyaschenko、Sascha Ott

    GRAPHICAL ABSTRACT Abstract λ3-phosphahexatrienes were prepared from ethoxyvinyl phosphinophosphonates using the phospha-Wittig–Horner reaction. The title compounds can be easily prepared in three steps starting from dichlorophosphines with good overall yields. Although these were found to be thermally unstable, these can be trapped, for instance, with methanol. The resulting methoxyphosphines are

    oxaphospholes is more exothermic for the trimethylsilyl‐containing substrates. The pathway to the latter compounds contains a 1,3‐shift of the group that stems from the acetylene terminus of the ketone substrates. For silyl substituents, the 1,3‐shift proceeds along a smooth potential energy surface through a transition state that is characterized by a pentacoordinated silicon center. In contrast, a high‐lying

  • Preliminary investigations on the chemistry of (η<sup>4</sup>-1-phosphabutadiene)tricarbonyliron complexes. Synthesis and X-ray crystal structure analysis of a (η<sup>4</sup>-2-phosphabutadiene)tricarbonyliron complex

    The reaction of the eta-2-complexed and half-masked dialdehyde [Fe(CO)4trans-(MeO)2CHCH = CHCHO}] with the 'phospha-Wittig' reagent [W(CO)5PHPhPO(OEt)2}] yields, after unmasking of the second aldehyde functionality, the 1-phosphabutadiene complex [Fe(CO)3eta-4-O = CHCH = CHCH = PPh[W-(CO)5]}], 4. The aldehyde functionality of 4 normally reacts with methyllithium, a phosphorus ylide, LiAlH4, or a dimercaptan to give the expected products in high yield without destruction of the (eta-4-1-phosphadiene)tricarbonyliron moiety. Thus, Fe(CO)3 is a convenient protecting group for the otherwise unstable 1-phosphadiene unit. Similarly, the reaction of isobutyraldehyde with the phospha-Wittig reagent [W(CO)5trans-PhCH = CHPHPO(OEt)2}] yields a (2- phosphabutadiene)-pentacarbonyltungsten complex whose X-ray crystal structure analysis shows a planar, transoid, but not delocalized 2-phosphadiene unit. Reaction of this complex with [Fe2(CO)9] gives a complex with a planar, cisoid and fully delocalized 2-phosphadiene unit according to the X-ray data.
