Treatment of (C5Me5)RuBr2(η3-CH2C(R)CH2) [R H (1a), Me (1b) with BrMg(CH2)4MgBr in ether afforded the RuII-alkyl-butadiene complexes, (C5Me5)Ru(η4-C4H6)(η1-CH2CHRCH3) [R H (2a), Me (2b)]. Labeling experiments have revealed a mechanism involving a double β-hydrogen elimination from ruthenacyclopentane intermediates and subsequent stepwise transfer of the hydrogen atoms to hydrogenate the η3-allyl ligand.
