Terminal Fe^I-N_2 and Fe^(II)···H-C Interactions Supported by Tris(phosphino)silyl Ligands
Chicago
Abstract
Taking hold: Monoanionic tris(phosphino)silyl ligands ([SiP6R-3]=[(2-R-2PC-6H-4)-3Si]−) stabilize unusual five-coordinate Fe^I complexes. The silane [SiP^(Ph)_3]H reacts with mesityliron(II) to give [(SiP^(Ph)_3)Fe^(II)Mes], which displays a C—H agostic interaction. Treatment with HCl and reduction affords the terminally bonded Fe^I—N_2 complex [(SiP^(Ph)_3)FeN_2] (see scheme; structures show only donor atoms of [SiP^(Ph)_3]), which yields hydrazine under protolytic conditions.
