Reversible C-H activation of a P(t)Bu(i)Bu2 ligand to reveal a masked 12 electron [Rh(PR3)2]+ cation.
[Rh(P(t)Bu(i)Bu(2))(2)][BAr(F)(4)], formed by removal of H(2) from [RhH(2)(P(t)Bu(i)Bu(2))(2)][BAr(F)(4)], is in rapid equilibrium between C-H activated Rh(III) isomers, but reacts as a masked 12-electron [Rh(P(t)Bu(i)Bu(2))(2)](+) Rh(I) cation.
