Article abstract of DOI:10.1021/om00127a027

[(η⁴-Ph₄C₄CO)(CO)₂Ru] ₂ and [(η⁴-Ph₂Me₂C₄CO)(CO) ₂Ru]₂ represent a new class of efficient precatalysts for homogeneous hydrogenation of alkenes, alkynes, ketones, aldehydes, and anthracene under moderate conditions. Mechanistic aspects have been investigated, and a basic catalytic cycle is proposed.
