The reduced lacunary polyoxotungstate, [PW11O39] 8-, reacts with the .CH2CH(OH)CH3 and .CH2C(CH3)2OH radicals via a mechanism involving β-hydroxide elimination to yield propene and 2-methyl propene respectively, and [PW11O39]7-. [PW 11O39]8- is also oxidized by methyl radicals in a reaction which yields methane as the major product. It is proposed that the reactions proceed via the formation of short lived transients with W-C σ bonds.
