Propylene Carbonate as a Solvent for Asymmetric Hydrogenations

Propylene Carbonate as a Solvent for Asymmetric Hydrogenations

A penny saved is a penny earned: The use of propylene carbonate as the solvent in iridium‐catalyzed hydrogenations of nonfunctionalized olefins allows efficient catalyst recycling through the formation of two‐phase mixtures with nonpolar solvents such as n‐hexane. In the picture, the hydrogenated te...

Zusammenfassung:A penny saved is a penny earned: The use of propylene carbonate as the solvent in iridium‐catalyzed hydrogenations of nonfunctionalized olefins allows efficient catalyst recycling through the formation of two‐phase mixtures with nonpolar solvents such as n‐hexane. In the picture, the hydrogenated tetrahydronaphthalene derivative is extracted into the hydrocarbon phase.
