Abstract
[^3^H]lithium 9βboratabicyclo[3.3.1]nonane, at specific activity of 52β55 Ci/mmol, was synthesized by reduction of BβOMeβ9βBBN with lithium tritide. Its reducing characteristics were illustrated by the synthesis of [17β^3^H] estradiol, [2β^3^H] dihydrotetrabenazine and 1β(hydroxy[^3^H]methyl)naphtalene, with good radiochemical yields and high specific activities.
