Partial Reduction of the N–O Functions of Partially Deprotonated Bis(hydroxylamine) Complexes
نویسندگان
چکیده
The reduction of a partially deprotonated bishydroxylamine complex {(Bu2Ga)2[cyclo-ON(Me)(CH2)2(Me)NO][HON(Me)(CH2)2(Me)(H)NO]} with a reagent composed of titanium tetrachloride and methyllithium leads to the reduction of one of the N–O groups to an amine function affording the salt {(Bu2Ga)[cycloON(H)(Me)(CH2)2NHMe]} {tBu2GaCl2}−. This has been characterised by 1H and 13C NMR spectroscopy, by elemental analysis and by single crystal X-ray diffraction, showing the neutral amine/hydroxylamine ligand to be present in its tautomeric aminoxide form. The molecules form hexameric cyclic aggregates by N–H· · ·Cl hydrogen bonds.
