Asymmetric homogeneous catalysis
Serves as a chiral rhodium(I) pre-catalyst for enantioselective transformations, where the BINOL-derived phosphorus ligands transfer chirality to the substrate. It is used in research aimed at preparing optically active, single-enantiomer products.
Asymmetric hydrogenation and C–C bond formation
Cationic rhodium(I) phosphite and phosphoramidite complexes of this type are established catalysts for asymmetric hydrogenation and rhodium-catalysed asymmetric conjugate (1,4-) addition chemistry. Specific scope should be confirmed against the user's own substrate and conditions.
Chiral ligand and methodology development
Used by synthetic and organometallic chemists evaluating BINOL-derived dioxaphosphepine ligands and rhodium catalyst systems, and in the screening of new enantioselective reactions and reaction conditions.
Pharmaceutical and fine-chemical intermediate synthesis
Applied at laboratory and process-development scale to construct stereodefined building blocks and intermediates where enantiocontrol is required. It is offered for research and manufacturing-development use, not as a finished pharmaceutical.

What is Bis[(10,11-η)-5-[(11bS)-dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-yl-κP4]-5H-dibenz[b,f]azepine]rhodium(I) tetrafluoroborate used for?
+
It is a chiral cationic rhodium(I) catalyst used in homogeneous asymmetric catalysis. The BINOL-derived phosphorus ligands make it suitable for enantioselective transformations such as asymmetric hydrogenation and rhodium-catalysed conjugate addition, and for chiral methodology development in fine-chemical and pharmaceutical-intermediate research.
What is the CAS number and molecular formula?
+
The CAS number is 1228149-03-8. The empirical formula is C68H44BF4N2O4P2Rh (Hill notation), corresponding to a molecular weight of 1204.75 g/mol. It is the single-enantiomer (S) rhodium(I) complex with a tetrafluoroborate counter-ion.
What grade and purity does Tech Serve Solutions supply?
+
Tech Serve Solutions supplies this material at an assay of ≥97% (by elemental analysis) as a research-grade catalyst. We do not represent it as USP, BP or EP pharmacopoeial grade. A current Certificate of Analysis is provided with each lot, and specifications can be confirmed at the time of enquiry.
How should this rhodium catalyst be handled and stored?
+
No GHS hazard classification was supplied to us for this compound; in the absence of full classification, handle it as a potentially hazardous research chemical. As an air- and moisture-sensitive organometallic, it should be handled under inert atmosphere using standard laboratory protective equipment and stored cool and dry. Always consult the accompanying Safety Data Sheet before use.
How is this product packed, shipped and exported?
+
It is packed in tightly sealed, appropriately labelled containers, typically under inert gas to protect the air-sensitive complex, with pack sizes from research quantities upward. Tech Serve Solutions exports worldwide with full documentation, including the Certificate of Analysis and Safety Data Sheet, and arranges transport in line with applicable regulations.
How do I request a sample or a quote?
+
Contact Tech Serve Solutions with your required quantity, purity and intended application, and our team will respond with availability, lead time and a formal quotation. Samples can be arranged for qualification, subject to availability and applicable regulatory requirements.
