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

In the crystal structure of the title compound (N4CPSTMAA), C(11)H(14)ClNO(3)S, 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.
