Polycarbon ligands: Synthesis and characterization of the phosphinodiynes Ph2PC≡C-C≡CR (R = But, Ph, SiMe3),the μ-η1,η2α, β-butadiynyl complexes Ru2(CO)6-(μ-PPh 2
The phosphino-diynes (PPh2C≡C-C≡CR) (R = But, Ph, SiMe3) are obtained in excellent yield from the corresponding diyne anions RC≡C-C≡C- by quenching with PPh2Cl. Monosubstitution on Ru3(CO)
