Reaction of dodecacarbonyltriruthenium with 7-oxabicyclo[2.2.1]hept-5-en-2-yl derivatives: synthesis of (µ3-η2-benzyne)-nonacarbonyldihydridotriruthenium and derivatives

Abstract

The thermal reaction of [Ru₃(CO)₁₂] with 7-oxabicyclo[2.2.1]hept-5-en-2-yl derivatives gave the corresponding [Ru₃H₂(CO)₉(7-oxabicyclo[2.2.1]hept-5-yn-2-yl)] clusters; treatment of the complex derived from 7-oxabicycio[2.2.1]hept-5-en-2-endo-yl benzoate with (CH₃)₃SiOSO₂CF₃ gave a mixture of [Ru₃H₂(CO)₉(benzyne)] and [Ru₃H₂(CO)₉(C₆H₃-OCOC₆H₅)].
