1,3-bis(2,6-diisopropylphenyl)-4,5-dihydroimidazole

Description:

1,3-bis(2,6-diisopropylphenyl)-4,5-dihydroimidazole, identified by its CAS number 258278-28-3, is a chemical compound characterized by its unique structure that features an imidazole ring substituted with two bulky 2,6-diisopropylphenyl groups. This compound is typically a solid at room temperature and exhibits a relatively high molecular weight due to the presence of the large isopropyl groups. The imidazole moiety contributes to its potential as a ligand in coordination chemistry and catalysis, while the bulky substituents may influence its solubility and reactivity. The presence of the diisopropylphenyl groups can enhance steric hindrance, potentially affecting the compound's interactions with other molecules. Additionally, the compound may exhibit interesting electronic properties due to the conjugation between the aromatic rings and the imidazole system. Its specific applications and reactivity would depend on the context of its use, particularly in organic synthesis or as a catalyst in various chemical reactions.

CAS: 258278-28-3

1,3-Bis(2,6-diisopropylphenyl)imidazolidin-2-ylidene (BDPI) is a metathesis catalyst that is used for the asymmetric synthesis of organic compounds. It is a palladium complex that undergoes reductive elimination to form a new carbon-carbon bond. BDPI has been shown to be selective for the formation of chiral products in cross-coupling reactions and has been used in the synthesis of natural products. The structure of BDPI was elucidated with x-ray crystallography and 13C NMR spectroscopy.
