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-. [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.
