N-(4-Chlorophenylsulfonyl)-2,2,2-trimethylacetamide

Abstract

In the crystal structure of the title compound (N4CPSTMAA), C11H14ClNO3S, the conformations of the N—H and C=O bonds in the amide group are anti to each other, similar to those observed in N-phenylsulfonyl-2,2,2-trimethylacetamide (NPSTMAA) and 2,2,2-trimethyl-N-(4-methylphenylsulfonyl)acetamide (N4MPSTMAA). The bond parameters in N4CPSTMAA are similar to those in NPSTMAA, N4MPSTMAA, N-aryl-2,2,2-trimethylacetamides and 4-chlorobenzenesulfonamide. The –SNHCOC– unit including the amide group is essentially planar and makes a dihedral angle of 82.2 (1)° with the benzene ring, comparable to the values of 79.1 (1) and 71.2 (1)° in NPSTMAA and N4MPSTMAA, respectively. The molecules in N4CPSTMAA are linked into a chain by intermolecular N—H...O hydrogen bonds.
