✦ Synopsis

Rh III carbonate generated from either a peroxocarbonate complex [RhCl(CO 4 )(PR 3 ) 3 ] or [RhCl 3 (PR 3 ) 3 ] and Na 2 CO 3 , is reduced to Rh I by deoxygenation of the carbonate moiety to CO 2 by an out-of-sphere phosphane. The reaction takes Scheme 1. Alternative pathways for CO 2 reaction with a Rh dioxygen complex [a
