Carbon–carbon bond formation through olefin–methylcarbyne linkage at a diruthenium centre: X-ray crystal structure of [Ru2(CO)(µ-CO){µ-η1,η3-C(Me)C(Me)CH2}(η-C5H5)2]
Abstract
Reaction of [Ru2(CO)2(µ-CO)(µ-CMe)(η-C5H5)2]+ with RCH![[double bond, length as m-dash]](https://www.rsc.org/images/entities/char_e001.gif)
CH2(R = H or Me) under u.v. radiation provides [Ru2(CO)(µ-CO){µ-η1,η3-C(Me)C(R)-CH2}(η-C5H5)2] which, for RH, may also be obtained by treatment of [Ru2(CO)(C2H4)(µ-CO)2(η-C5H5)2] with MeLi, HBF4 successively; the structure of [Ru2(CO)(µ-CO){µ-η1,η3-C(Me)C(Me)CH2}(η-C5H5)2] has been determined by X-ray diffraction.
