A hemispherical vanadium oxide cluster has a cavity that can accommodate a bromine molecule. It was found that a bromine molecule trapped in the cavity was polarized and that an alkane molecule ...

Alkanes: Bromination (substitution reaction) R-H + Br2 → R-Br + HBr ( colorless) (amber) (colorless) UV light splits the bromine molecule into two reactive radicals, resulting in a very slow loss of ...

Figure 1: Closed loop bromine-mediated light-alkane conversion scheme to produce value-added chemicals and fuels. Figure 2: Catalytic performance expressed as single-pass carbon yields (Y) of ...

Nature - Alkanes to amines by bromine. Chemists have been seeking simple ways of inserting nitrogen or other elements into alkanes — simple hydrocarbons with just single bonds — to turn them ...
