Popis:	Treatment of RuHCl(Cyttp) (1) with PhC≡C−C≡CPh in benzene produced RuCl(η 3 -PhC 3 CHPh)(Cyttp). Reaction of 1 with MeO 2 CC≡CCO 2 Me yielded RuCl(MeO 2 CC=CHCO 2 Me)(Cyttp). Acetylide complexes RuCl(C≡CR)(Cyttp) (R=Ph, (CH 2 ) 5 CH 3 )) were produced when (1) was treated with HC≡CR. Reactions of RuH 4 (Cyttp) (2) with MeO 2 CC≡CCO 2 Me and PhC≡CPh gave fac-Ru(η 4 -MeO 2 CCH=CHCO 2 Me)(Cyttp) and Ru(PhC≡CPh)(Cyttp), respectively. Reaction of (2) with 1-octyne produced Ru(C≡C(CH 2 ) 5 CH 3 ) 2 (Cyttp). Reaction of (2) with excess phenylacetylene produced Ru(C≡CPh)(η 3 -PhC 3 CHPh)(Cyttp)
