C−H Bond Activation by Air-Stable [(Diimine)MII2-OH)]22+ Dimers (M = Pd, Pt)

Abstract: Selective C-H bond functionalization is a potentially valuable approach for synthesis in areas ranging from fuels and commodity chemicals to pharmaceuticals. 1 C-H activation studies in our laboratory have focused on models of the Shilov system, 2 particularly methylplatinum cations [(diimine)Pt II (Me)(solv)] + (2, diimine ) ArNdC(Me)-C(Me)dNAr; solv ) 2,2,2-trifluoroethanol (TFE), H 2 O). 3 These cations are able to activate a variety of R-H bonds to form [(diimine)Pt II (R)(solv)] + complexes (3), as shown … Show more

“…Kinetics for the reaction between [(diimine)Pt(µ-OH)] 2 2+ (1a), indene and acid (either aqueous HBF 4 or BF 3 in TFE) were performed using an analogous procedure to that described previously for the reaction between 1a, cyclohexene and acid. 1 These experiments indicated that these reactions appeared to follow the same pathway.…”

“…The Pt hydroxy-bridged dimer [(diimine)Pt(µ-OH)] 2 ·[BF 4 ] 2 (1a), 1 Pd bis(aquo) dication [(diimine)Pd(OH 2 ) 2 ]·[BF 4 ] 2 (2b) 2 and solutions of BF 3 in TFE 3 were synthesized using literature procedures. All reactions described were conducted under an atmosphere of air, and solvents were not dried prior to use unless otherwise noted.…”
