Abstract

The anionic Group 13 NHC analogues [(CHNDipp)2E]− (E = B or Ga) display contrasting reactivity towards the half-sandwich titanium imido complex Cp*TiCl(NtBu)py; while the gallium system undergoes salt metathesis yielding the first example of a titanium gallyl compound, the more nucleophilic boryl anion generates a dearomatized pyridyl fragment via attack at the ligand 2-position.
