  Intermolecular conjugate radical addition reactions of secondary and tertiary alkyl radicals derived from the corresponding alkyl iodides to activated olefins such as α,β-unsaturated esters, amides, imides, nitriles, and sulfones are described. The adduct radicals are trapped by either diphenyl(trimethylstannyl)phosphane or the commercially available diphenyl(trimethylsilyl)phosphane as chain transfer

  The synthesis of monosubstituted and 1,4-substituted cyclohexanes bearing one of the title groups is described. The conformational analysis of these compounds was studied by 19F NMR spectroscopy at various temperatures. Chemical shifts for each conformer above the coalescence temperature were obtained by binomial regression from low temperature values, allowing the high precision determination of the

  S-methyl xanthates, dl-trans-2-dimethylaminocyclohexyl S-methyl xanthalate was rearranged without elimination to the corresponding dithiolcarbonate while the cis isomer suffered over-all elimination. It has been suggested that the dimethylamino group attached to the carbon carrying the xanthate group induces the rearrangement. Other examples studied support this mechanism. 2-Benzamidoethyl S-methyl and

  A novel process for the one-step conversion of a variety of primary and secondary alcohols into their O -alkyl- S -methyl dithiocarbonates using methyl iodide catalyzed by the Triton-B/CS2 system was developed. Thus, O -alkyl- S -methyl dithiocarbonates were obtained in very good to excellent yields. This protocol is mild and efficient compared to other methods.
