A New Method of Generation of Bismuthonium Ylides and their Efficient Trapping with Sulphenes

Bismuthonium ylides are generated by reacting triphenylbismuth oxide or dichloride with sodium salts of cyclic and open chain 1,3-dicarbonyl compounds; ylides from open chain 1,3-dicarbonyl compounds, which readily decompose on standing to produce C-phenylation products, can be efficiently trapped by sulphenes to afford 1,3-oxathiole-3,3-dioxides in good yields.

Triphenylbismuthonio-4,4-dimethyl-2,6-dioxocyclohexane-1-ide and Triphenylbismuthonio-4,4-dimethyl-2,6-dioxo-3,5-dioxan-1-ide. Preparation and Properties of the Stable Bismuthonium Ylides

The title two bismuthonium ylides were obtained in pure form and their reactions with some electrophiles were studied.In contrast with stable ylides of arsenic and antimony, these bismuthonium ylides readily react sith aldehydes and isothiocyanates but th

Pentavalent Organobismuth Reagents. Part 3. Phenylation of Enols and of Enolate and other Anions

The phenylation of enols and of enolate anions of ketones, β-diketones and keto esters has been studied using a range of Bi reagents.Under basic conditions C-phenylation is observed and, even hindered, perphenylated compounds are easily synthesized.Under neutral and acidic conditions ordinary ketones do not react and enolic systems give O-phenylation.A number of other anions have been phenylated under basic conditions, including the key compound indole wich mainly gave 3-C-phenylation.All these reactions can be supposed to have one of two alternative mechanisms, which parallel the two mechanisms proposed for the phenylation of phenols.
