Wittig-olefination via an yttrium-coordinated betaine

We report the synthesis of an yttrium phosphonium methylide complex and its reaction with benzophenone to form an excedingly rare hydrocarbon soluble metal-coordinated betaine. While this reaction models the C-C σ-bond formation step of the Wittig reaction under salt-conditions, addition of Ph 3PO to the betaine complex results in formation of 1,1-diphenylethene.
