Interligand Interactions in Half-Sandwich Nickelacarboranes with Phosphine Ligands: Away from Skeletal Rearrangements
摘要:
Reactions of nickel(II) phosphine complexes [(dppe)NiCl2], [(MePh2P)2NiCl2] and [(Ph3P)2NiCl2] with C-substituted nido-carboranes [7-R-nido-7,8-C2B9H11]− (R = Me, Ph, C(NHCy)2+) were studied. The reactions with [(dppe)NiCl2] lead to the corresponding nickelacarboranes 3,3-(dppe)-1-R-closo-3,1,2-NiC2B9H10 with absent or negligible steric interactions between the ligands. The reactions of [(MePh2P)2NiCl2]
