| 1926 Chem. Abstr. XX. 3685 Propadiene was prepd. by dropping the dibromopropylene into a flask contg. Zn dust and EtOH and heating. 1939 Jrnl. Amer. Chem. Soc. LXI. 751/2 Particularly interesting cases are the propane-propene mixtures..or propyne-propadiene mixtures from isomerization studies. 1991 Inorg. Chem.
