Chemical and structural characterization of some π-allylic derivatives of rhodium(III)

Add time:07/19/2019    Source:sciencedirect.com

The reaction of rhodium trichloride trihydrate and trans, trans, trans-1,5,9-cyclo- dodecatriene in boiling ethanol yields the red, diamagnetic dichloro(cyclododeca-1,5-dienyl)rhodium(III), insoluble in all common organic solvents.This compound is polymeric through chlorine bridges and reacts with many Lewis bases (e.g., carbon monoxide, amines, olefins) to give octahedral derivatives such as C12H19RhCl12B2 (B is a monodentate basic ligand).The chemical and structural characterization of this compound is reported through a study of its derivatives by X-rays, IR and NMR spectra and a possible mechanism is proposed.
