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."}],"publication":"Polymer","type":"journal_article"}]
