2,2-Dichloro-N-(3,4-dimethylphenyl)acetamide

Abstract

In the title compound, C10H11Cl2NO, the N—H bond is syn to the 3-methyl substituent in the aromatic ring, similar to that observed in N-(3,4-dimethylphenyl)acetamide and to the 3-chloro substituent in 2,2-dichloro-N-(3,4-dichlorophenyl)acetamide, and contrasting with the anti conformation observed for the 3-methyl substituent in 2,2,2-trichloro-N-(3,4-dimethylphenyl)acetamide. On the other hand, it is anti to the C=O bond. An intermolecular N—H...O hydrogen bond links molecules into infinite chains along the b axis.
