A simple one-pot route to stable formamidinatoiodidolanthanoid(iii) complexes from lanthanoid metals

A number of formamidinatoiodidolanthanoid(iii) complexes, [Ln(DFForm)(2)I(thf)(2)] and [Ln(DFForm)I-2(thf)(3)] (DFFormH = N,N '-bis(2,6-difluorophenyl)formamidine) and [Ln(DippForm)I-2(thf)(3)] (DippFormH = N,N '-bis(2,6-diisopropylphenyl)formamidine) have been synthesized in good yields by one-pot direct reactions of the corresponding free metals with iodine and DFFormH or DippFormH in suitable ratios and are stable to rearrangement.

Automated summary

A series of formamidinatoiodidolanthanoid(iii) complexes have been synthesized in good yields by direct reactions of free metals with iodine and DFFormH or DippFormH in appropriate ratios, and are stable without rearrangement.
