1-Penten-4-yne reacts with bromine at$-80°$C to produce 4,5-dibromopentyne as follows
$\mathrm{C}{\mathrm{H}}_2=\mathrm{C}\mathrm{H}-\mathrm{C}{\mathrm{H}}_2-\mathrm{C}\equiv \mathrm{C}\mathrm{H}+\mathrm{B}{\mathrm{r}}_2\stackrel{-80°}{\to }\mathrm{C}{\mathrm{H}}_2\mathrm{B}\mathrm{r}-\mathrm{C}\mathrm{H}\mathrm{B}\mathrm{r}-\mathrm{C}{\mathrm{H}}_2-\mathrm{C}\equiv \mathrm{C}\mathrm{H}$
