Allenylidene
complexes [Ru(η5-C9H7)(CCCPh2){P(OR)3}(PPh3)][PF6] (R = Et (1), Me (2)) have been
synthesized by the reaction of the complexes [Ru(η5-C9H7)Cl{P(OR)3}(PPh3)] with 1,1-diphenyl-2-propyn-1-ol in the presence of NaPF6. Addition of different nucleophiles to complex 1 allows
the synthesis of new allenyl or alkynyl ruthenium complexes depending
on the regiochemistry of the reaction. Unexpected complexes [Ru(η5-C9H7){κ3(C,C,C)-C(R2PCH2CHCH2)CCPh2}{P(OEt)3}][PF6] (R = iPr (9a),
Ph (9b)), containing an unusual κ3(C,C,C)-ligand have been obtained from the
reaction of the allenylidene complex 1 with alkenylphosphane
Ph2PCH2CHCH2 (ADPP) or iPr2PCH2CHCH2 (ADIP). The formation of these complexes is proposed to proceed
through an intermediate, [Ru(η5-C9H7)(CCCPh2){P(OR)3}{κ1(P)-R2PCH2CHCH2}][PF6].
