Donor stabilization of Sn(II) and Pb(II) halides with 1,1'-ferrocenylene bridged bisphosphanes has been explored for Fe(CHP(CH)) (dppf), and Fe(CHPH(CH)). These bisphosphanes are reacted with SnBr and PbCl with and without additional Lewis acid (AlCl) 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.
已对用1,1'-二茂铁撑桥连双膦对卤化锡（II）和卤化铅（II）进行供体稳定化进行了研究，涉及二（二苯基膦基）二茂铁（Fe(CHP(CH)) (dppf)）和二（二甲基膦基）二茂铁（Fe(CHPH(CH))）。这些双膦与溴化锡和氯化铅在有和没有额外路易斯酸（氯化铝）的情况下反应，形成无环和环状供体加合物，其中后者代表双膦鎓四价体。由于观察到溶液中的动态交换，除了单晶X射线衍射（SC-XRD）外，表征还包括溶液和固态核磁共振，并通过密度泛函理论（DFT）计算进行修正。
