The novel ruthenaphosphaalkenyl complex [Ru{P-CH(SiMe3)}Cl(CO)(PPh3)2], prepared from [RuHCl(CO)(PPh3)3] and Me3SiC=P, exhibits ambiphilic behavior, reacting at phosphorus with both nucleophiles and electrophiles. Its reaction with Li(pz') or K[HB(pz')3] (pz' = pz, pz*) affords [Ru{?1-N:?2-P,C-P(pz')-CH(SiMe3)}(CO)(PPh3)2], a rare example of a ruthenium(0) ?2-phosphaalkene complex and the first example of a P-pyrazolylphosphaalkene. Conversely, reaction with the electrophilic PhHgCl leads to metalation at phosphorus, affording [Ru{?1-P(HgPh)-CH(SiMe3)}Cl2(CO)(PPh3)2].
