  text: Abstract Donor stabilization of Sn(II) and Pb(II) halides with 1,1?-ferrocenylene
    bridged bisphosphanes has been explored for Fe(C5H4P(C6H5)2)2 (dppf), and Fe(C5H4PH(C4H9))2.
    These bisphosphanes are reacted with SnBr2 and PbCl2 with and without additional
    Lewis acid (AlCl3) forming acyclic and cyclic donor adducts from which the latter
    represent bisphosphoniotetrylenes. Since dynamic exchange in solution is observed,
    characterization includes solution and solid-state NMR in addition to SC-XRD,
    amended by DFT calculations.

  text: A lithium halide exchange reaction at low-temperature, via the treatment of
    2,6-di(isopropyl)phenyllithium on 1,1′-bis-(dichlorophosphino)ferrocene, resulted
    in the first isolated example of an aryl-substituted diphospha [2]ferrocenophane
    (diphospha [2]FCP) 2. Although compound 2 did not show any recognizable thermal
    reaction at higher temperature (up to 350 °C), its tert-butyl-substituted counterpart
    1 underwent a clean selective heat-mediated P–C cleavage reaction, followed
    by an inter-molecular rearrangement, to produce a P–P fused bis [3]ferrocenophane
    3 with all-trans oriented P-chain, which upon further heating gave a polyferrocenylphosphane
    tBu-[Fc’P2]n-tBu (4). Since polymer 4 is insoluble in common organic solvents,
    it has been characterized with solid-state techniques, including solid-state NMR.
    Density functional theory (DFT) has further been employed to identify possible
    pathways for P–C bond cleavage on 1 and 2, as well as to evaluate accessible
    pathways for further polymerization toward 4.
