Stabilization of a Chelate Tautomer of Phenylacetylide
摘要:
Complex [Ir(mu-Cl)(COE)(2)](2) (1; COE = cis-cyclooctene) reacts with Li[C5H4(CH2)(2)N(CH3)(2)] to give Ir{eta(5)-C5H4(CH2)(2)N(CH3)(2)}(COE)(2) (2), which affords IrI2-{eta(5)-C-5,kappa-N-[C5H4(CH2)(2)N(CH3)(2)]} (3), by addition of I-2. The reaction of 3 with phenylacetylene yields Ir{eta(5)-C-5, sigma- C-a,sigma-C-b-[C5H4(CH2)(2)N(CH3)(2)C-a=CHC-(CH)(4)-C-b]} (4), which has been characterized by X-ray diffraction analysis.
