• W1566742549 abstract "Abstract Protonation of dimethylacetamide (DMA), tetramethylurea (TMU), ethyl acetate (EtOAc) and dimethylsulphoxide (DMSO) by the complex acid HCl-SbCl5 in 1,2-dichloroethane has been studied. Enthalpy changes for the interaction between the donor compounds (D) and excess HCl-SbCl5 to give the protonated complexes [DH]+SbCl6− have been determined calorimetrically. From NMR experiments it was found that the acidic proton in the [DH]+SbCl6− complexes was in slow exchange on the NMR time scale with excess acid at 37°C. The observed chemical shift values of the acidic proton in the [DMAH]+ and [EtOAcH]+ complexes were in close agreement with values reported for the protonated bases in HSO3F or HSO3F-SbF5, which indicates that complete proton transfer takes place in the hexachloroantimonate complexes. In solutions containing the donor compounds in excess, half-protonated complexes [D2H]+SbCl6− were formed. The acidic proton chemical shifts in these complexes were found at 8–9 ppm lower field than in the monoprotonated complexes indicating strong hydrogen bonding in the [D2H]+ cations. Exchange between complexed and excess donor was found to be rapid on the NMR time scale. D·SbCl5 donor-acceptor adducts have also been studied. Protonation and adduct formation are considered to take place at the CO and SO oxygen atoms." @default.
