N-(4-Bromo-phenyl-sulfon-yl)-2,2,2-tri-methyl-acetamide.

ABSTRACT: The conformations of the N-H and C=O bonds in the SO(2)-NH-CO-C group of the title compound (N4BPSTMAA), C(11)H(14)BrNO(3)S, are trans to each other, similar to what is observed in N-(4-chloro-phenyl-sulfon-yl)-2,2,2-trimethyl-acet-amide (N4CPSTMAA) and 2,2,2-trimethyl-N-(4-methyl-phenyl--sulfon-yl)acetamide (N4MPSTMAA). The bond para-meters in N4BPSTMAA are similar to those in N4CPSTMAA, N4MPSTMAA, N-aryl-2,2,2-trimethyl-acet-amides and 4-bromo-benzene-sulfonamide. The benzene ring and the SO(2)-NH-CO-C group in N4BPSTMAA form a dihedral angle of 82.8?(1)°, comparable with the values of 82.2?(1)° in N4CPSTMAA and 71.2?(1)° in N4MPSTMAA. N-H?O hydrogen bonds form a centrosymmetric ring characterized by an R(2) (2)(8) motif.
