Integrated electrochemical-chemical oxidation mediated by alkoxysulfonium Ions

Generation of carbocations by the "cation pool" method followed by reaction with dimethyl sulfoxide (DMSO) gave the corresponding alkoxysulfonium ions. Alkoxysulfonium ions could also be generated by in situ DMSO trapping of electrochemically generated carbocations. The resulting alkoxysulfonium ions were transformed into carbonyl compounds by treatment with triethylamine. The present integrated electrochemical-chemical oxidation can be applied to the oxidation of diarylmethanes to diaryl ketones, toluenes to benzaldehydes, and aryl-substituted alkenes to 1,2-diketones. Moreover, the oxidation of unsaturated compounds bearing a nucleophilic group in an appropriate position gives cyclized carbonyl compounds.

Generation of diarylcarbenium ion poolsviaelectrochemical C-H bond dissociation

The "cation pools" of diarylcarbenium ions have been generated by the low-temperature electrochemical oxidation of diphenylmethane derivatives. In addition to diphenylmethanes having various substituents, 9,10-dihydroanthracene, dibenzosuberane, and xanth

Carbon-13 Nuclear Magnetic Resonance Studies of Carbocations. 10. Variation of Cationic Carbon Chemical Shifts with Increasing Electron Demand in 1,1-Diaryl-1-methyl (Benzhydryl) Carbocations

A series of 28 1-X-phenyl-1-Z-phenyl-1-methyl (benzhydryl) carbocations, where the X and Z substituents have been varied over the range of electron demand (3,4-CH2CH2O, 11; 4-OCH3, 12; 4-CH3, 13; 4-F, 14; 4-H, 1; 4-CF3, 15; 3,5-(CF3)2, 16), have been prepared from the corresponding alcohols by ionization in superacids and their 13C NMR spectra recorded at low temperatures (-70 to -10 deg C).Plots of the substituent chemical shifts of the cationic carbons (ΔδC+) at -70 deg C against ?C+ are linear for the electron donors (Z = 3,4-CH2CH2O to Z = H) of 13 - 16 and 1 but deviate upward from this correlation line (relative shielding) for the electron acceptors (Z = H to Z = 3,5-(CF3)2).The plots of the highly stabilized cations 11 and 12 approximate shallow curves where groups more electron demanding than 4-CH3 cause relative shielding of the cationic carbon.All these plots are interpreted in terms of competing resonance and localized inductive ?-polarization effects.
