چکیده
The six-membered thio-pyran ring in the title compound, C(24)H(19)BrS, adopts an approximate envelope conformation, with the S atom displaced by 0.26 (1) Å and the 2-methyl-ene C atom by -0.54 (1) Å from the plane of the other four sp(2)-hydridized C atoms. The methyl substituent on the methyl-ene carbon lies in a pseudo-axial position with the phenyl ring in a pseudo-equatorial position.

In the title compound, C35H31NO5, the piperidine ring has an envelope conformation, with the phenyl-substituted C atom adjacent to the methyl-ene C atom as the flap. This flap atom deviates by 0.633 (2) Å from the mean plane of the other five essentially coplanar atoms in the ring (r.m.s. deviation = 0.044 Å). Intra-molecular C-H⋯O hydrogen bonds form S(7) and S(9) ring motifs. In the crystal, ...

The title compound, C21H12Br2F13NO·2CH3OH, was obtained by condensation of 4-methyl-1-(1H,1H,2H,2H-perfluoro-oct-yl)pyridinium iodide and 3,5-di-bromo-4-hy-droxy-benzaldehyde, followed by deprotonation. It crystallizes as a methanol disolvate and exhibits short O-H⋯O hydrogen bonds and a disordered perfluoro-alkyl chain [occupancy ratio 0.538 (7):0.462 (7)]. Significant π-π stacking inter-actio...
متن کاملA facile synthesis of novel herbicidal 1-phenyl-piperazine-2,6-diones.
Novel 1-phenyl-piperazine-2,6-diones were prepared by a new facile synthetic route using methyl N-substituted iminomonoacetate as starting material. The structures of these compounds were established by (1)H-NMR, (13)C-NMR and GC/MS. 2-(4-Chloro-5-cyclo-pentyl-oxy-2-fluorophenyl)-tetrahydro-2H-pyrido-[1,2-a]-pyrazine-1,3-(4H,6H)-dione displayed the greatest herbicidal activity.
