Clearly different : The mechanism of CH activation by air‐ and water‐tolerant complexes of the type [{(diimine)Pd(μ‐OH)} 2 ] 2+ (see scheme; Ar= t Bu 2 C 6 H 3 , solv=MeOH or trifluoroethanol) and [(diimine)Pd(OH 2 ) 2 ] 2+ has been investigated. Surprisingly, there are significant mechanistic differences in activation by the dimeric Pd complex and the analogous Pt species , with the Pd species found to be considerably more reactive.
