The complex, [Rh(triphos)CO][PF6] {triphos = bis(2-diphenylphosphinoethyl)phenyl phosphine}, 4, reacts with aryloxides, ArO- {Ar = C6H5, C6H4-p-CH3, C6H4-p-OCH3}. The formation and subsequent chemistry of the resulting aryloxycarbonyl complexes were observed by FTIR spectroscopy. These aryloxycarbonyl complexes are formed and decay via different pathways involving the fac- and mer-isomers of Rh(triphos)(CO)(OAr). Decarbonylation of Rh(triphos)(CO)(OAr) forms Rh(triphos)OAr, {Ar = C6H5 (1), C6H4-p-CH3, (2) C6H4-p-OCH3 (3)}, while elimination of the aryloxide via a different pathway can also reform [Rh(triphos)CO][PF6], 4.
