一般描述
[1,4-Bis(diphenylphosphino)butane](1,5-cyclooctadiene)rhodium(I) tetrafluoroborate is a rhodium-based catalyst used for regioselective hydrogenation and enantioselective reductive amination reactions.
应用
[1,4-Bis(diphenylphosphino)butane](1,5-cyclooctadiene)rhodium(I)tetrafluoroborate can be used as a catalyst for the:
- Regioselective hydrogenation of thebaine to synthesize tetrahydrothebaine.
- Enantioselective reductive amination of α-ketoacids with benzylamines to synthesize α-N-benzylamino acids.
- Stereoselective hydrogenation of α-(hydroxymethyl)-acrylate derivatives to synthesize 3-hydroxy-2-methylpropanoates.

The intramolecular anti-Markovnikov hydroamination of 1-(3-aminopropyl)vinylarenes in the presence of a readily available rhodium catalyst to form 3-arylpiperidines is reported. In contrast to intermolecular hydroamination of vinylarenes, which occurred in high yields in the presence of rhodium catalysts containing DPEphos

Low-field benchtop nuclear magnetic resonance (BT-NMR) spectrometers with Halbach magnets are being increasingly used in science and industry as cost-efficient tools for the monitoring of chemical reactions, including hydrogenation. However, their use of low-field magnets limits both resolution and sensitivity.
