Abstract
Alkenes are hydroborated with LiBH4 in the presence of UCl4, NdCl3 or ZrCl4, by following the reactivity sequence tetramethylethylene > 1-me thylcyclohexene much greater than 2-methylpropene or hex-l-ene (no rea ction); treatment of U(BH4)(4) with tetramethylethylene affords the ur anium tetrakis(thexylborohydride) [U(BH(3)R)(4)] (R = CMe(2)CMe(2)H).
