To a solution of 0.051 g (0.1 mmol) Hg(SePh)2 in 6 mL DMF were added 0.027 g (0.1 mmol) HgCl2, and the solution was stirredfor 10 min. Thereafter,0.049 g (0.2 mmol) PR2R’ (R = tert-butyl;R’ = 4-N,N-dimethylaniline) were added, and the mixture was further stirred for 1 h. The solution was then filtered over Celite,and 6 mL isopropanol was layered over the mother liquor. After 1 week, yellow crystals suitable for X-ray analysis were obtained.Yield: 0.034 g, 52% based on Hg(SePh)2.Properties: yellow crystalline substance. Melting point: 148-150C. Anal.

Phosphine ligand
Chiral phosphine ligands in asymmetric synthesis. Molecular structure and absolute configuration of (1,5-cyclooctadiene)-(2S,3S)-2,3-bis(diphenylphosphino)butanerhodium(I) perchlorate tetrahydrofuran solvate

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.932710-63-9,4-(Di-tert-butylphosphino)-N,N-dimethylaniline,as a common compound, the synthetic route is as follows.

General procedure: [{Pd(mu-Cl)(kappa2N,C-C6H4CH2NMe2)}2] (500 mg, 0.91mmol) and a phosphine (1.82 mmol) were fed into a Schlenk flask under Ar atmosphere.Then, toluene (8 mL) was added to the mixture at room temperature, and the reactionmixture was stirred at 50 C overnight. The solvent was evaporated, and the resultingmass was purified by recrystallization from ether, ethanol, or pentane.

To a solution of {Te((2,6-OCH3)2C6H3)}2 (0.053 g, 0.1 mmol) inacetonitrile (5 mL), PdI2 (0.036 g, 0.1 mmol) was added and thesolution was stirred for 2.5 h. In the next step, (4-(N,N-dimethylamino)phenyl)di-tert-butyl phosphine (0.053 g, 0.2 mmol) wasadded and the mixture was stirred for a further 2.5 h. The turbidsolution was filtered through filter paper followed by filtrationthrough Celite. The slow evaporation of solvent afforded air-stabledark red crystals suitable for X-ray analysis.
