Vinyl carbocations: solution studies of alkenyl(aryl)iodonium triflate fragmentations.
Generation of vinyl cations is facile by fragmentation of alkenyl(aryl)iodonium trifluoromethanesulfonates. Kinetics and electronic effects were probed by (1)H NMR spectroscopy in CDCl(3). Products of fragmentation include six enol triflate isomers in addition to iodoarenes. The enol triflates arise from direct reaction of a triflate anion with the starting iodonium salts as well as triflate re...
متن کاملEnantioselective carbolithiation of S-alkenyl-N-aryl thiocarbamates: kinetic and thermodynamic control.
The addition of n-butyllithium to alkenylthiocarbamates in the presence of (-)-sparteine or the (+)-sparteine surrogate leads to asymmetric carbolithiation, and returns enantiomerically enriched thiocarbamate derivatives of secondary thiols. In THF, with the (+)-sparteine surrogate, in situ aryl migration leads to an enantiomerically enriched tertiary thiol derivative. Remarkably, the two pseud...
متن کاملTandem copper-catalysed aryl and alkenyl amination reactions: the synthesis of N-functionalised indoles.
A Cu-diamine complex effectively catalyses tandem C-N bond formation on 2-(2-haloalkenyl)-aryl halide substrates, to deliver a series of N-functionalised indoles. Anilines, amides and carbamates are all effective coupling partners under the developed conditions.
متن کاملCarbon monoxide free aminocarbonylation of aryl and alkenyl iodides using DMF as an amide source.
[reaction: see text] Palladium-catalyzed coupling reaction of N,N-dimethylformamide with aryl or alkenyl halides successfully proceeded in the presence of phosphoryl chloride to afford the corresponding tertiary amides in good yields.
متن کاملIsothiourea-Catalysed Acylative Kinetic Resolution of Aryl-Alkenyl (sp2 vs. sp2 ) Substituted Secondary Alcohols.
The non-enzymatic acylative kinetic resolution of challenging aryl-alkenyl (sp2 vs. sp2 ) substituted secondary alcohols is described, with effective enantiodiscrimination achieved using the isothiourea organocatalyst HyperBTM (1 mol %) and isobutyric anhydride. The kinetic resolution of a wide range of aryl-alkenyl substituted alcohols has been evaluated, with either electron-rich or naphthyl ...
