Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 224311-51-7, Name is 2-(Di-tert-Butylphosphino)biphenyl, name: 2-(Di-tert-Butylphosphino)biphenyl.
The reaction of [RuCp(PR3)(CH3CN)2]PF6, where R=Ph and Cy, with ferrocenyl acetylene (HC?CFc) affords the first eta2-allenyl carbene complexes [CpRu(=C(Fc)-eta2-CH=C=CH(Fc))(PR3)]PF6. The new type of C-C bond formation is affected by the strong electronic coupling of the ferrocenyl moiety with the conjugated allenyl carbene unit, which facilitates transient vinylidene formation with subsequent alkyne insertion into the Ru=C double bond. The vinylidene intermediate appears to occur only in the presence of bulky substituents of the phosphine co-ligand. For small R=Me, head-to-tail coupling between two alkyne molecules involving phosphine migration is preferred, giving the more usual eta3-allyl carbene complex [CpRu(=C(Fc)-eta3-CHC(Fc)CHPMe3)]PF6. The X-ray structure of an eta2-allenyl carbene complex is presented.
