The reaction of [ (C9H7) 2LnH]2 . 2THF with NaH in THF genera tes the dimeric organolanthanide hydrides [ (C9H7) 2LnH]2. 4THF NaCL. Then the hydrides react with the unsaturated carbonyl compounds. citronellal, bihydrocarveol, phenylacetate, methyl cinn amte.Organolanthanide hydrides selectively reduce the carbonyl function,selectivity,islOO%.The activity of unsaturated carbon yl compounds :aldelhydes>ketone>ester.And the organolanthanide hydrides may promote the claisen rearrangement.
