Abstract

Two iodo derivatives, [closo-B₁₀H₉-1-I]^2- (1) and [closo-B₁₀H₈-1,10-I₂]^2- (2), were obtained from the parent [closo-B₁₀H₁₀]^2- anion in a two-step process and about 60% and 80% overall yields, respectively. Molecular and crystal structures of 2[Pr₄N] were established with XRD methods: I422; a = b = 10.1531(1) Å, c = 18.0149(2) Å; α = β = γ = 90°; Z = 2. Synthetic applications of 1[Bu₄N] were demonstrated in a Pd(0)-catalyzed cross-coupling reaction with 4-MeOC₆H₄MgBr.
