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

The conformations of the N-H and C=O bonds in the SO2-NH-CO-C group of the title compound (N4BPSTMAA), C11H14BrNO3S, are trans to each other, similar to what is observed in N-(4-chlorophenylsulfonyl)-2,2,2-trimethylacetamide (N4CPSTMAA) and 2,2,2-trimethyl-N-(4-methylphenylsulfonyl) acetamide (N4MPSTMAA). The bond parameters in N4BPSTMAA are similar to those in N4CPSTMAA, N4MPSTMAA, N-aryl-2,2,2-trimethylacetamides and 4-bromobenzenesulfonamide. The benzene ring and the SO2-NH-CO-C group in N4BPSTMAA form a dihedral angle of 82.8 (1)degrees, comparable with the values of 82.2 (1)degrees in N4CPSTMAA and 71.2 (1)degrees in N4MPSTMAA. N-H center dot center dot center dot O hydrogen bonds form a centrosymmetric ring characterized by an R-2(2)(8) motif.
