Preparation of NHC Stabilized Al(III)fluorides: Fluorination of [(SIMes)AlMe3] with SF4 or Me3SnF
Various reaction routes have been developed to synthesize the N-heterocyclic carbene (NHC) stabilized Al(III) fluorides [(SIMes)Al(F)3] (2) and [(SIMes)Al(F)Me2] (3) through fluorination of [(SIMes)AlMe3] (1) (SIMes: 1,3-bis(2,4,6-trimethylphenyl)-imidazolidin-2-ylidene) with fluorinating agents such as SF4, SF6 and Me3SnF. The reactivity of 2 was investigated towards a F/Cl exchange reaction by treating it with Me3SiCl.
