Abstract

Hydrogen spillover is mechanistically poorly understood, due to the H˙ donor complexity. We show that HV(CO)₄dppe (1) transfers H˙ to MoO₃ in separate H⁺ and e⁻ transfer steps. This is analogous to hydrogen spillover from Pt to MoO₃ and suggests that 1 is a good model for H˙ adsorbed on Pt.
