Abstract

A polyoxometalate with two alkyl thiol appendages, Q4[SiW 11O40(SiCH2CH2CH2SH) 2] (Q = ammonium salt) stabilized the formation of palladium nanoparticles. This tethered polyoxometalate-palladium binary catalyst was effective for the aerobic oxydehydrogenation of vinylcyclohexene and vinylcyclohexane to styrene as the major product via activation of the allylic, tertiary carbon-hydrogen bond.
