Synthesis and characterization of 1-amino-4-methylthio-2-nitro-1,3-butadienes

1,3,4,4-Tetrachloro-4-(4-chlorophenylsulfanyl)-2-nitrobuta-1,3-diene

“…The C-C bond lengths of the butadiene chain agree well with corresponding distances in a similar compound (Surange et al, 1997). The chlorophenyl ring and the butadiene group are inclined at an angle of 59.5 (1) .…”

3,4,4-Trichloro-2-nitro-1-propylsulfanyl-1-(4-thiomorpholinyl)buta-1,3-diene

“…closer to cisoid than to transoid, the C4-C3-C2-C1 torsion angle being À64.3 (3) . The C-C bond lengths within the butadiene unit are similar to those in related compounds (Surange et al, 1997;Ibis et al, 2006). The thiomorpholine ring adopts a chair conformation, as shown by the puckering angles of ' = 1(3) and = 10.2 (4) (Cremer & Pople, 1975).…”

New Piperazine Derivatives Synthesized from Thio‐Substituted Polyhalogeno‐2‐nitro‐1,3‐butadienes

“…X-Ray structural analysishave shown that the nitrodiene 4g is Eisomer with a non-planar and close to cisoid configuration. Some E-and Z-isomer thiosubstitue nitrodiene compounds have been reported [34][35][36][37][38][39][40][41] that the observed values in compound 4g is consistent with the corresponding values in these similar compounds.…”
