A new route to arsonium, stibonium, and bismuthonium 2,2-dimethyl-4,6-dioxo-1,3-dioxanides - The crystal structures of Ph 3E-C6H6O4 (E = As, Sb, Bi) [1]

The ylides Ph3E-C6H6O4 [3; E = As (a), Sb (b), Bi (c)] have been prepared through the reaction of Ph 3E and 5-bromo-2,2-dimethyl-4,6-dioxo-1,3-dioxin (4) followed by addition of triethylamine in good yields. The crystal structures of 3 are reported.

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
