Sažetak

In orur work on hydrogen isotope effects we needed a symmetrical olefin specifically labeled on the d61Uble bond wi,th tI'itium. The simplest way to achieve this seemed to be the preparatiion of an acetylene and the subsequent catalytic reduction with tritium gas to the corresponding olefin. 4-0ctyne was therefore prepaired from n-propyl bromide and d:irsodium acetylide in liquid ammonia by a procedure which was found to· be more practical than the published 101I1es1• 2• 4-0cty.ne was then ireduced wirthout solvent in the presence of Lindlarr catalyst Wlith tritium gas which was produced by ele~trolysis of tritilated sulfuriic acid. The distilled product was pure 4--0eterne as shown by vaipor phase chromatography.
