✦ Synopsis

The half-sandwich titanium trimethyl complex (η 5 -C 5 H 4 CMe 2 Ar)TiMe 3 (Ar = 3,5-Me 2 C 6 H 3 ) reacts with the Lewis acid B(C 6 F 5 ) 3 to give the ionic Ti IV ansa-cyclopentadienyl-arene complex [(η 5 ,η 6 -C 5 H 4 CMe 2 Ar)TiMe 2 ]-[MeB(C 6 F 5 ) 3 ]. In bromobenzene solvent, addition of more B(C 6 F 5 ) 3 leads to C 6 F 5 /Me exchange and, subsequently, to [ ]
