Low-valent iron complexes stabilised by a bulky guanidinate ligand: Synthesis and reactivity studies

A toluene-capped guanidinato iron(i) complex [(Pipiso)Fe(η6-toluene)] (Pipiso≤[(DipN)2C(cis-NC5H8Me2-2,6)]-) was prepared by magnesium metal reduction of {[(Pipiso)FeII(μ-Br)]2} in toluene. The reactivity of the closely related FeI-FeI multiply bonded species, {[Fe(-Pipiso)]2} towards a range of unsaturated small molecule substrates was investigated, and found to be broadly similar to that of low-valent β-diketiminato iron complexes. That is, its reaction with CO yielded the iron(i) carbonyl complex [(Pipiso)Fe(CO)3], whereas reaction with CO2 formed the same product via an apparent reductive disproportionation of the substrate. In contrast, reaction between {[Fe(-Pipiso)]2} and CS2 led to reductive C≤S bond cleavage and the isolation of {[(Pipiso)Fe]2(-S)(-CS)}. Different reactivity was seen with AdN3 (Ad≤1-adamantyl), which was reductively coupled by the iron(i) dimer to give iron(ii) hexaazenyl complex {[(Pipiso)Fe]2(-AdN6Ad)}. CSIRO 2014.

Reactions of alkali metal amides or phosphides with the bulky carbodiimide, ArN=C=NAr (Ar = C6H3Pri2-2,6), followed by aqueous work-ups, have yielded several guanidines, ArNC(NR 2)N(H)Ar (R = cyclohex
