Article abstract of DOI:10.1039/c39870001778

Acid, at a concentration frequently present in solvents such as dichloromethane, causes rapid interconversion of fac- and mer- (dppm=Ph2PCH2PPh2, L=PEt3 or PEt2Ph) via a 7-co-ordinate hydride intermediate, ⁺: convenient syntheses are developed, based on these protonation reactions, including the conversion of fac- into the more useful mer-isomer.
