General Description

4,4-Dimethyl-2-phenyl-2-oxazoline is an 2-aryl-2-oxazoline and has been tested as as ligand for the Suzuki coupling reaction of aryl bromides and arylboronic acids. 4,4-Dimethyl-2-phenyl-2-oxazoline forms mildly hygroscopic complexes, of general formulae [ZnX₂(ox)₂] (ox =4,4-Dimethyl-2-phenyl-2-oxazoline), with ether solutions of [ZnX₂] (X = Cl, Br, I).Except ZnI₂, which does not form an isolable complex due to steric reasons.
