Cyanoacetylene synthesis

9synthesis methods
Cyanoacetylene is not commercially available, but can be prepared on a several gram scale by the dehydration of  propynamide (propiolamide) with Phosphorus(V) Oxide (eq 1). The reactants are well ground together under nitrogen, and  upon subjection of the resulting solid mixture to high temperature treatment, propynenitrile is collected as a distillate in a  receiver held at 5 °C.
