Novel synthesis of borane complexes of cyclic phospanes using ruthenium-catalyzed olefin metathesis
Schuman M., Trevitt M., Redd A., Gouverneur V.
Grubbs' catalyst [Cl2Ru{P(C2H11)2}2 = CHPh] can be used to synthesize borane complexes of cyclic phosphanes by ring-closing metathesis reactions. This strategy has been applied, for example, to the preparation of a borane-protected bisphosphanes [Eq. (1)].
