Abstract

Results for the pulse radiolysis of B10H14 in selected solvent systems are reported. In polar solvents the solvated electron is rapidly scavenged by B10H14 with k >~ 2x1010 1. mol-1 s-1. In H2O, CH30H and C2H50H a transient optical absorption (G x ε ≈ 104 1. mol-1 cm-1) attributed to boranyl radicals is observed. A lower yield is observed in aqueous acid and hydrocarbon solutions and in the presence of electron scavengers. The results are consistent with an electron scavenging reaction leading to formation of a boranyl radical.
