However, this method is difficult because ammonia is toxic. However, it is flammable, and in order to synthesize long-chain acetylene compounds, it is necessary to increase the solubility of the alkyl halide and the reaction must be carried out under pressure.There are many problems in implementing it industrially. there were.

These methods give good results when R2 in the general formula (n) is a hydrogen atom, that is, an acetylide of unsubstituted acetylene; In this case, there was a problem that a satisfactory yield was not obtained. For example, in the case of l-propynyl sodium, various solvents were investigated, and even under the best conditions using dimethyl sulfoxide, the yield was only 36% (
