New rhodacyclopentane with phenylvinylidene substituents, mer-[R[upper bond 1 start]h{CH₂C(=CHPh)C(=CHPh )C[upper bond 1 end]H₂}Cl(PMe₃)₃]. Structure and formation through concerted cycloaddition of phenylallene molecules to [RhCl(PMe₃)₃]

Abstract

[RhCl(PMe₃)₃] reacts with an excess of phenylallene to give a new rhodacyclopentane, mer-[R[upper bond 2 start]h{CH₂C(=CHPh)C(=CHPh )C[upper bond 2 end]H₂}Cl(PMe₃)₃] 1, which is not obtained via the reaction of [RhCl(η²-CH₂=C=CHPh)(PMe₃ )₃] 2 with phenylallene.
