Kinetic studies on the interconversion between trans-RhCl(FcC≡CSiMe3)(PPri3)2 (2a) and trans-RhCl-{=C=C(Fc)(SiMe3)}(PPri3)2 (Ba) (Fc = ferrocenyl group) provided the following activation parameters for the forward and the backward reactions: ΔH? = 19.8 ± 0.2 kcal mol-1 and ΔS? = -4.8 ± 0.7 eu for 2a to 3a and ΔH? = 22.7 ± 0.1 kcal mol-1 and ΔS? = -8.6 ± 0.4 eu for 3a to 2a. The values are consistent with the isomerization mechanism via a sigmatropic 1,2-migration of the SiMe3 group.

The complexes C5H5Rh(C2R2)PPri3 (III, IV) are prepared from trans-RhCl(C2R2)(PPri3)2 (I, II) and NaC5H5.Protonation of III (R = Me) gives salts of the cation i3>+ which contains the allylic ligand in the anti-configuration.At room temperature, a rearrangement to the syn-isomer occurs.The reaction of IV (R = Ph) with CF3CO2H yields the vinyl complex C5H5Rh(CPh=CHPh)(O2CCF3)PPri3 (VII) which reacts with NH4PF6 or CF3CO2H in methanol to form the metallaindene derivative VIII.The X-ray structure of VIII has been determined.
