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. 4,4-Dimethyl-2-phenyl-2-oxazoline may be used in the synthesis of an ester-ammonium salt via rupture of oxazoline ring.
