3-(4-Chlorophenyl)-5-phenyl-4,5-dihydro-1,3-oxazole

Abstract

In the title compound, C<inf>15</inf>H<inf>12</inf>ClNO, the isoxazoline ring adopts an envelope conformation with the C atom bearing an unsubstituted phenyl ring as the flap atom. The chlorinated phenyl group is nearly in-plane with the four coplanar atoms of the heterocycle and the corresponding mean planes enclosing an angle of 1.16(7)°. The unsubstituted phenyl group attached to the envelope flap atom approaches a nearly perpendicular orientation relative to the isoxazoline ring with a dihedral angle of 74.93(7)°. In the crystal, weak C-H?O, C-H?N and C-H?? interactions connect the molecules into layers perpendicular to the a axis.
