| | Physical properties | Butyldi-1-adamantylphosphine is a white to yellow solid with a melting
point of 100°C and an estimated boiling point of 449.6±12.0°C. Store at
room temperature, it is air sensitive. | | Uses | suzuki reaction | | Uses | CataCXium A is a catalyst. CataCXium A is an electron-rich phosphine ligand used for palladium catalyzed cross-coupling reactions like Heck and Suzuki coupling reactions. | | Uses | cataCXium A or di-adamantylalkylphosphine is a bulky and electron-rich phosphine ligand that is highly effective for palladium catalyzed cross-coupling reactions such as Heck and Suzuki coupling, Buchwald-Hartwig amination of aryl chlorides, and α-arylation reactions of ketones. Other applications:- palladium-catalyzed carbonylation of aryl and heteroaryl halides
- palladium-catalyzed synthesis of (hetero)aromatic nitriles
- palladium-catalyzed aminocarbonylation of aryl halides
| | General Description | Sold in collaboration with Solvias AG | | Synthesis | Phosphonium salt (2.2 mmol) was added to a cooled solution (- 78 °C) of
Et3N
(4.44 g, 44 mmol) in di-n-butyl ether (20 mL). The reaction mixture was
stirred at -78 °C for 5 h and then allowed to warm gradually to r.t.
The solvent was removed under vacuum and the residue was dissolved in
degassed EtOH (5 mL). After stirring for 15 min, the solid was filtered
off and dried to yield the desired phosphine, which can be further
purified by crystallization from EtOH. Butyldi-1-adamantylphosphine,
yield 90%. 31P NMR (C6D6)δ: 24.9. Mp 108-110°C. IR (KBr): 3425 (m, br),
