Synthesis, crystal structure and Hirshfeld surface analysis of -(4-fluoro-phen-yl)--isopropyl-2-(methyl-sulfon-yl)acetamide.

The synthesis and crystal structure of the title compound, CHFNOS, which is related to the herbicide flufenacet, are presented. The dihedral angle between the amide group and the fluorinated benzene ring is 87.30 (5)° and the N-C-C-S torsion angle defining the orientation of the methyl-sulfonyl substituent relative to the amide group is 106.
