Enanti-opure (S)-butan-2-yl N-(4-x-phen-yl)thio-carbamates, x = NO₂, OCH₃, F, and Cl.

ABSTRACT: The structures of (S)-butan-2-yl N-(4-nitro-phen-yl)thio-carbamate, C₁₁H₁₄N₂O₃S, (I), (S)-butan-2-yl N-(4-meth-oxy-phen-yl)thio-carbamate, C₁₂H₁₇NO₂S, (II), (S)-butan-2-yl N-(4-fluoro-phen-yl)thio-carbamate, C₁₁H₁₄FNOS, (III), and (S)-butan-2-yl N-(4-chloro-phen-yl)thio-carbamate, C₁₁H₁₄ClNOS, (IV), all at 100 K, have monoclinic (P2₁) symmetry with two independent mol-ecules in the asymmetric unit. The Flack absolute structure parameters in all cases confirm the absence of inversion symmetry. The structures display N-H⋯S hydrogen bonds, resulting in R ₂ ²(8) hydrogen-bo
