The triruthenium ynenyl cluster complex [Ru 3 (μ 3 ‐η 2 ‐apyr)(μ‐η 3 ‐MeCH=CC≡CMe)(μ‐CO) 2 (CO) 6 ] ( 2 ; Hapyr = 2‐aminopyrimidine) has been prepared in two steps from [Ru 3 (CO) 12 ], 2‐aminopyrimidine and 2,4‐hexadiyne. Its reactivity with two conjugated diynes has been studied. With 2,4‐hexadiyne, it affords [Ru 3 (μ 3 ‐η 2 ‐apyr){μ‐η 5 ‐MeC≡CC=CMeC(=CHMe)C≡CMe}(μ‐CO) 2 (CO) 5 ] ( 3 ), which contains a diynedienyl ligand that arises from the coupling of 2,4‐hexadiyne with the hex‐2‐yn‐4‐en‐4‐yl ligand of 2 , whereas the reaction of complex 2 with diphenylbutadiyne gives [Ru 3 (μ 3 ‐η 2 ‐apyr){μ 3 ‐η 7 PhC≡CC=CPhCMe=CC(=CHMe)C(C≡CPh)=CPh}(μ‐CO)(CO) 6 ] ( 4 ). Complex 4 contains an unprecedented diynetetraentriyl ligand that arises from the coupling of two diphenylbutadiyne molecules with the hex‐2‐yn‐4‐en‐4‐yl ligand of 2 .
