In exploring one-electron carbon-carbon bonds, I had noted previously[cite]10.59350/88k04-2×509[/cite] that both hexafluoroethane and ethane itself could each lose an electron to produce such species. A discussion developed in which a molecule isoelectronic with ethane, namely the methyl-λ1-borane radical (H ₃ B-CH ₃ ) was proposed by Jacob.
