Abstract
The in situ generated ruthenium acetylide complex C5Me5(PPh3)RuC⋮CPh (1) was found to catalyze the cross-coupling reaction of terminal and internal alkynes to yield functionalized enynes. An intermediate β-agostic species was isolated from the reaction of C5Me5(PPh3)(Cl)RuCCHBu-t (2b) with 2-butyne in the presence of NaOMe.
