A well-defined iron complex system was established using PNNP-R (R = Ph and Cy) as a strong σ-donating ligand with a rigid meridional tetradentate structure. Reactive Fe(0) complexes [{Fe(PNNP-R)}2(μ-N2)] were synthesized by a reaction of the corresponding iron dihalide with NaBEt3H and structurally characterized. The reaction proceeded via the iron dihydride intermediate [Fe(H)2(PNNP-R)], which underwent H2 reductive elimination, supporting the hemilabile behavior of PNNP-R. [{Fe(PNNP-R)}2(μ-N2)] catalyzed the dehydrogenative coupling of silanols with silanes to selectively form various hydrosiloxanes, which are important building blocks for the synthesis of a range of siloxane compounds. This system exhibited higher catalytic efficiency than the previously reported precious-metal-catalyzed systems.

Reaction of lithium diphenylphosphide with vicinal nitrogen disubstituted polyimines such as 1,8-naphtyridine, 4'-phenyl-2,2',6',2''-terpyridine, 2,2'-bipyridine or 1,10-phenanthroline produces in high yield a new series of heterofunctional ligands.
