Probing the non-innocent nature of an amino-functionalised β-diketiminate ligand in silylene/iminosilane systems
Electron-rich β-diketiminate ligands{,} featuring amino groups at the backbone β positions (“N-nacnac” ligands) have been employed in the synthesis of a range of silylene (SiII) complexes of the type (N-nacnac)SiX (where X = H{,} Cl{,} N(SiMe3)2{,} P(SiMe3)2 and Si(SiMe3)3). A combination of experimental and quantum chemical approaches reveals (i) that in all cases rearrangement to give an aza-butadienyl SiIV imide featuring a contracted five-membered heterocycle is thermodynamically favourable (and experimentally viable); (ii) that the kinetic lability of systems of the type (N-nacnac)SiX varies markedly as a function of X{,} such that compounds of this type can be isolated under ambient c…
