AbstractAbstract
[en] The synthesis is based on reduction of lithium [1-14C]heptanoate with lithium aluminium hydride in boiling tetrahydrofurane with subsequent decomposition of the resulting complex using 48% hydrobromic acid. The resulting [1-14C]heptan-1-ol, following addition of 96% H2SO4 is converted to 1-bromo[1-14C]heptane. The lithium [1-14C]heptanoate used for the synthesis was prepared by introducing a solution of n-hexyl lithium in n-hexane in a vessel containing n-hexane and 14CO2 at 195 K. The technique does not require the separation of intermedite products. The obtained radiochemical yield of 1-bromo[1-14C]heptane was 81% with respect to the starting Ba14CO3 (purity of 97%). (J.C.)
