The conditions for and products of thermolysis of 4-azahepta-1,6-diyne, (HC≡C-CH2)2NH, have been investigated by microwave, photoelectron, i.r., and mass spectrometric techniques. Prop-2-ynylideneamine, HC≡C-CH=NH, is produced in good yield as well as penta-3,4-diene-1-yne, CH2=C=CH-C≡CH, from (HC≡C-CH2)2NH. Ionisation potential and vibrational data for HC≡C-CH=NH, CH2=C=CH-C≡CH, and the precursors have been obtained. The ionisation energies have been assigned with the aid of theoretical calculations. Photoelectron data on 3-aminopropyne, HC≡CCH2NH2, have also been obtained.
