The reaction of Os3(CO)9(C2R2) (R = Tol, Ph; Tol = p-C6H4Me) with Cp(CO)2W≡CTol (Cp = η5-C5H5) produces an alkylidyne-alkyne complex CpWOs3(CO)10(μ3-??2-C 2R2)(μ3-CTol) [1a (R = Tol), 1b (R = Ph)], which is converted to two isomeric allyl complexes CpWOs3(CO)10(μ3-η3-C 3R2Tol) (2a,b and 3a,b) upon thermolysis. Complexes 3a,b, in which the allyl ligand is π-coordinated to the tungsten atom, undergo consecutive allyl C-C bond cleavage to afford trialkylidyne complexes CpWOs3(CO)9(μ3-CR)2(μ 3-CTol) (5a,b) via alkylidyne-alkyne complex CpWOs3(CO)10(μ3-η2-C 2R2)(μ3-CTol) or CpWOs3(CO)10(μ3-η3-C 2RTol)(μ3-CR) (4a,b), together with formation of CpWOs3(CO)8(μ3-η 2-⊥-C2R2)(μ3-CTol) or CpWOs3(CO)8(μ3-η 2-⊥-C2RTol)(μ3-CR) (6a,b) as a minor product.
