Abstract

The η2-alkyne complex (C5H5)(PMe 3)2Ru(HC≡CMe)+PF6-, which was isolated from a reaction of HC≡CMe with (C5H 5)(PMe3)2RuCl, undergoes first-order rearrangement to give (C5H5)(PMe3) 2Ru=C=C(H)Me+ PF6-; at higher tempreatures in MeCN, this vinylidene complex cleanly regenerates HC≡CMe and forms (C5H5)(PMe3)2Ru(MeCN) +PF6-.
