| Abstract |
Herein, we report on the first synthesis and structural characterization of the iron based aminoborane complexes [Fe(PNP)(H)(eta(2):eta(2)-H2B=NR2)](+) (R=H, Me). These species are formed upon protonation of the borohydride complex [Fe(PNP)(H)(eta(2)-BH4)] by ammonium salts [NH2R2](+) (R=H, Me). For R=Me, the reaction proceeds via the cationic dinuclear intermediate [\Fe(PNP)(H)\(2)(mu(2),eta(2):eta(2)-BH4)](+). A mechanism for the reaction is proposed based on DFT calculations that also indicate the final aminoborane complex as the thermodynamic product. All complexes were characterized by NMR spectroscopy, HRMS, and X-ray crystallography. |
