Abstract

The reaction of diarylbutenynylruthenium complexes [Ru(?³- C(C=CC₆H₄R)=C(R')C₆H₄R)(PMe ₃)₄]⁺ (C₆H₄R = C ₆H₄-4-Bu, Ph, C₆H₄-4-Me; R' = H, Me) with dimethylmagnesium yields the cyclometalated ruthenaindene complexes [Ru(C(C=CC₆H₄R)=C(R)C₆H₃R)(PMe ₃)₄] with ruthenium incorporated into the five-membered ring of an indene. The reaction involves the initial formation of methylruthenium complexes, which then rearrange with the elimination of methane to yield the product. The complexes [Ru(C(C=CC₆H₄R)=C(R) C₆H₃R)(PMe₃)₄] (C₆H ₄R = C₆H₄4-^tBu, R' = H.; C ₆H₄R = Ph, R' = Me) were crystallographically characterized. © 2009 American Chemical Society.
