N-Ethyl-2-[1-(2-hydroxy-6-methoxyphenyl)ethylidene]hydrazinecarbothioamide

N-Ethyl-2-[1-(2-hy­droxy-6-meth­oxy­phenyl)ethyl­idene]hydrazinecarbothio­amide

In the title compound, C(12)H(17)N(3)O(2)S, the dihedral angle between the mean planes of the hydrazinecarbothio-amide group and the benzene ring is 86.8 (4)°. In the crystal, inter-molecular O-H⋯S hydrogen bonds link the mol-ecules into chains along [001]. The crystal studied was an inversion twin, the refined ratio of the twin components being 0.98021 (3):0.01978 (7).

2-Chloro-N-chloro­methyl-N-(2-ethyl-6-methyl­phen­yl)acetamide

The title compound, C(12)H(15)Cl(2)NO, was synthesized as an inter-mediate for the synthesis of the herbicide Acetochlor. The crystal structure exhibits weak inter-molecular C-H⋯O hydrogen bonds, which link the mol-ecules into zigzag chains along the b axis.

Ethyl 2-hydroxy-2-phenyl-2-(thiazol-2-yl)acetate

This short note describes the synthesis of the title compound through spontaneous aerobic oxidation of ethyl 2-phenyl-2-(thiazol-2-yl)acetate. Due to the prevalence of such functional motifs in biologically active substances, we believe the oxidation encountered highlights an important degradation pathway worthy of note.

N-Ethyl-2-[1-(2-hy­droxy­naphthalen-1-yl)ethyl­idene]hydrazinecarbo­thio­amide

In the title compound, C15H17N3OS, the dihedral angle between the mean planes of the 2-hy-droxy-napthyl ring system and the hydrazinecarbo-thio-amide group is 73.7 (3)°. In the crystal, weak O-H⋯S and C-H⋯O inter-actions and π-π stacking inter-actions involving one of the hy-droxy-napthyl rings with a centroid-centroid distance of 3.6648 (14) Å are observed, forming infinite chains along [010]....
