Binap and MeOBiphep biarylbis(phosphane) complexes of Ru II are shown to undergo a series of stereospecific P−C bond cleavage reactions. The products are novel cationic chiral arenebis(phosphane) compounds which contain stereogenic Ru centers. Upon further solvolysis in alcohols, additional P−C cleavage reactions lead to stereogenic P atoms. Several novel olefin π‐bonding modes are recognised, including one in which only a single arene carbon atom i.e. an η 1 π‐bond, weakly coordinates to Ru II .
