| Abstract: | 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−. [PW11O39]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. |
