Pentamethylcyclopentadienylindium (Cp*In) as Terminal Ligand in the Chemistry of Chromium
摘要:
The reaction of Cp*In with the Cr(CO)(5)-transfer agent Cr(CO)5(C8H14) (C8H14 = cis-cyclooctene) results in the formation of Cr(Cp*In)(CO)(5) (1), in which Cp*In acts as an electron pair donor. Compound 1 was characterised by spectroscopic data and by an X-ray analysis. The structure of 1 is compared with the analogous gallium compound Gr(Cp*Ga(CO)(5) (2).
