1-(3-Chloro-4-fluorophenyl)-5-(2-diazoacetyl)-4-phenylpyrrolidin-2-one

Abstract

In the title compound, C18H13ClFN3O 2, the pyrrolidine ring adopts an envelope conformation and the planar part is rotated by 4.3 (6)° from the plane of the benzene ring and is almost perperdicular both to the diazoacetyl unit [dihedral angle = 78.93 (7)°] and the phenyl ring [dihedral angle = 86.07 (7)°]. In the crystal, mol-ecules are linked into a three-dimensional framework by C - H⋯O inter-actions. The mol-ecular conformation is stabilized by an intra-molecular C - H⋯O hydrogen bond.
