Two new triynes, C6Me3-1,3,5-[CH2O(p-C6H4)C
CH]3 (3) and C6Me3-1,3,5-[CH2O(p-C6H4)PhC(OH)CCH]3 (5), have been prepared and used for the facile synthesis of several tris(vinylideneruthenium) and tris(allenylideneruthenium) complexes via metal-mediatedactivation and tautomerization or isomerization and dehydration of the alkyne moieties,respectively. Complexes C6Me3-1,3,5-{[CH2O(p-C6H4)CH=C=Ru(dppe)2Cl]BF4}3 (6) andC6Me3-1,3,5-{[CH2O(p-C6H4)PhC=C=C=Ru(dppe)2Cl]BF4}3 (8) were obtained by activationof 3 and 5 by [RuCl(dppe)2]BF4. C6Me3-1,3,5-[CH2O(p-C6H4)CH=C=Ru(PCy3)2Cl2]3 (7) andC6Me3-1,3,5-{[CH2O(p-C6H4)PhC=C=C=Ru(PCy3)(p-cymene)Cl]OTf}3 (9) resulted from thereaction of 3 with [RuCl2(p-cymene)]2/2PCy3 and of 5 with [RuCl(PCy3)(p-cymene)]OTf.
