Anodic olefin couplingreactions using a tosylamine trapping group have been studied. The cyclizations are favored by the use of a less-polar radical cation and more basic reaction conditions. The most significant factor for obtaining good yields of cyclic product is the use of the more basic reaction conditions. However, a number of factors including the nature of both the solvent and the electrolyte

Reaction of α,β-ethylenic and acetylenic phosphonicacidmonoesters with (biscollidine)iodine(I) or (biscollidine)bromine(I) hexafluorophosphate led to α,β-unsaturated halides by, without precedent, dephosphorylation reactions.

The transylidation reactions of polymer-bound selenium bromide with alkylidenetriphenylphosphoranes 1 gave resin 2, which is sufficiently reactive to undergo Wittig-type reactions to afford the vinylic selenide resins 3. Cleavage gave ketones and aldehydes under different conditions.

[(Ph)3PBr][Br7], [(Bz)(Ph)3P]2[Br8], [(n-Bu)3MeN]2[Br20], [C4MPyr]2[Br20] ([C4MPyr] = N-butyl-N-methylpyrrolidinium), and [(Ph)3PCl]2[Cl2I14] were prepared by the reaction of dibromine and iodine monochloride in ionic liquids. The compounds [(Ph)3PBr][Br7] and [(Bz)(Ph)3P]2[Br8] contain discrete pyramidal [Br7]− and Z-shaped [Br8]2– polybromide anions. [(n-Bu)3MeN]2[Br20] and [C4MPyr]2[Br20] exhibit new infinite
