Terminal alkynes in reactions with 2,2,2-tribromobenzo[ d]-1,3,2-dioxaphosphol.

The article investigates the reaction of dioxaphosphol with unsubstituted alkylacetylene. The reaction with propargyl chloride with phosphol resulted in two phosphorus-containing substances which gave rise to characteristic doublet signals of benzophosphorinines which were converted by hydrolysis into the corresponding acids.
