Synthesis, characterization and reactivity of dinuclear rhenium complexes containing hemilabile phosphines as ligands: X-ray structures of diax-[Re2(CO)8{κ1(P)-Ph2P(CH2)2CN}2], [Re2(CO)8{μ:κ3(P,C,C)-iPr2NP(CH2CHCH2)2}] and diax-[Re2(CO)8(PPh3){κ1(P)-p

Reaction of [Re2(CO)8{μ:κ3(P,C,C)-p-MeOC6H4P(CH2CHCH2)2}] (6) with nucleophile molecules, such as CO and PPh3, demonstrates that the diallylphosphine can indeed act as hemilabile ligand in the rhenium dinuclear complex, while [Re2(CO)8{μ:κ3(P,C,C)-iPr2NP(CH2CHCH2)2}] (4) does not react in presence of nucleophiles.107
