Description

General description

ImPy-Dipop-Dipp is an NHC precursor developed in the Szostak group. The ligand is useful in a range of catalytic transformations, and is particulary well suited to the following: Suzuki-Miyaura cross-coupling of aryl mesylates and tosylates, Suzuki–Miyaura cross-coupling of nitroarenes (Ar–NO₂), Buchwald-Hartwig amination of alkyl sulfoxides

Application

Suzuki-Miyaura cross-coupling of aryl mesylates and tosylates Suzuki–Miyaura cross-coupling of nitroarenes (Ar–NO₂) or aryl sulfamates Buchwald-Hartwig amination of alkyl sulfoxides or aryl sulfamates

Features and Benefits

ImPy-Dipop-Dipp is an asymmetric NHC ligand precursor. It forms air-and moisture stable complexes with transition metals and is particulary effective in palladium catalyzed cross-coupling reactions.
