"It is possible to use carbon monoxide in direct reductive amination. The process can be catalyzed by rhodium, iridium or ruthenium."
Unlocking the Mysteries of Science
Selective reductive amination
Reducing without external source of hydrogen allows to avoid hydrogenation functional and protecting groups.
Carbon Monoxide as reducing agent
Steel is being produced in big amounts every year. Carbon monoxide is the main waste in this production and it should be used for industry use.
