Bis[2-(diadamantylphosphino)ethyl]amine
Bis[2-(diadamantylphosphino)ethyl]amine (CAS 1086138-36-4) is an air-sensitive tertiary aminophosphine with the molecular formula C44H69NP2 and a molar mass of 673.97 g/mol. The structure pairs two bulky, electron-rich di(1-adamantyl)phosphino groups with a central secondary-amine donor, giving a tridentate P,N,P scaffold. It is used principally as an ancillary ligand in homogeneous transition-metal catalysis and organometallic chemistry. Tech Serve Solutions supplies it as a research-grade reagent (97% assay).

Tridentate P,N,P ligand for catalysis
The two phosphine donors and the central amine nitrogen allow the molecule to bind a metal centre in a tridentate, pincer-type fashion. This geometry is widely exploited to stabilise well-defined homogeneous catalysts.
Ligand for transition-metal complexes
It coordinates a range of transition metals to form defined organometallic complexes for research. The bulky, electron-rich adamantyl substituents impart strong electron donation and steric protection at the metal.
Homogeneous catalysis research
As an electron-rich, sterically demanding ancillary ligand, it is studied in catalyst development for bond-forming and bond-activation reactions. It is intended for laboratory and process-development use.
Organometallic and coordination chemistry
The compound serves as a building block in organometallic and coordination-chemistry investigations where a robust, tunable phosphine-amine donor set is required.

What is Bis[2-(diadamantylphosphino)ethyl]amine used for?
+
It is used mainly as a tridentate P,N,P (pincer-type) ligand in homogeneous transition-metal catalysis and organometallic chemistry. Its electron-rich di(1-adamantyl)phosphino groups and central amine donor help form and stabilise well-defined metal complexes for research and process development.
What is the CAS number and molecular formula of Bis[2-(diadamantylphosphino)ethyl]amine?
+
Its CAS number is 1086138-36-4 and its molecular formula is C44H69NP2 (empirical formula, Hill notation), with a molecular weight of 673.97 g/mol. The MDL number is MFCD17018779.
What grade and purity does Tech Serve Solutions supply?
+
We supply Bis[2-(diadamantylphosphino)ethyl]amine as a research/technical-grade reagent with a typical assay of 97%. We do not represent it as USP, BP or EP pharmacopoeial grade. A certificate of analysis can be provided with each batch on request.
How should Bis[2-(diadamantylphosphino)ethyl]amine be handled and stored safely?
+
As a trialkylphosphine it is air- and moisture-sensitive and prone to oxidation, so it should be handled and stored under inert gas (nitrogen or argon). It is classed under transport UN 3335 and carries a German water-hazard rating of WGK 3 (severe hazard to water), so contamination of drains and watercourses must be avoided. Always consult the current Safety Data Sheet before use and follow good laboratory practice with appropriate personal protective equipment. The reported melting point is 217-222 °C.
How is Bis[2-(diadamantylphosphino)ethyl]amine packed, shipped and exported?
+
It is packed in sealed, inert containers suitable for an air-sensitive solid and is available in laboratory and bulk research quantities. As it falls under transport classification UN 3335, it is shipped as dangerous goods with the appropriate documentation; Tech Serve Solutions handles export paperwork and global logistics in line with the destination requirements.
How do I request a sample or quote?
+
Contact Tech Serve Solutions with your required quantity, purity and destination, and we will respond with availability, lead time and a formal quotation. Samples and a certificate of analysis can be arranged for evaluation.
