Abstract
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 product, can be efficiently trapped by sulphenes to afford 1,3-oxathiole-3,3-dioxides in good yields.Keywords
