Abstract

The reported activity of nanoscale NaH and titanocene towards catalytic reduction of terminal alkenes using molecular hydrogen is surprising considering that both NaH bulk and titanocene are inactive by themselves. In this work, the role of Ti dopants, the importance of NaH nanoclusters and role of the solvent (THF) and cocatalyst (titanocene) are investigated using density functional theory techniques. A plausible mechanism is proposed to explain the origin of the selective catalytic activity. A step-by-step reaction pathway starting with hydrogen chemisorption near the titanium atoms on the NaH nanoparticle surface followed by the reaction of the activated hydrogen with terminal alkenes via a five-membered ring intermediate are discussed.
