A New Approach to The Synthesis of Phosphoranes Based on the Reaction of Benzo[d]-1,3,2-Dioxaphospholes, Having β- or γ-Unsaturated Group in a Substituent, with Compounds Containing Multiple Bonds

Abstract

We developed a new approach to the synthesis of phosphoranes and carba phosphatranes on the basis of the reaction of benzo[d]-1,3,2-dioxaphospholes, having β- or γ-unsaturated group in a substituent, with such compounds containing multiple bonds, such as hexafluoroacetone, chloral, and diethylacetylenedicarboxylate.

Keywords:

• Phosphorane
• benzo-1,3,2-dioxaphosphole derivatives
• hexafluoroacetone
• chloral
• diethylacetylenedicarboxylate
• carbaphosphatranes
• X-ray analysis
