Four N-chloropiperazines [ 1,4-dichlro-trans-2,5-dimethylpiperazine, 1-chloro-4-(4-nitrophenyl)piperazine, 1-chloro-4-phenylpiperazine and 1-chloro-4-(2-methoxyphenyl) piperazine ] are conformationally studied by 13C DNMR. Ab initio energy minimisations and geometry optimisations were also carried out on these compounds and on 1,4-dichlropiperazine using the PCM model at the HF/6-31G* level. Results are discussed in terms of previous related work.
Head-to-Tail Assemblies of Dipolar, Piperazine-Linked Chromophores: Synthesis, X-ray Structure, and Dielectric Characterization
Katz, H. E.,Schilling, M. L.
, p. 7554 - 7557 (2007/10/02)
A dimer and a mixture of oligomers of acceptor-substituted anilines were prepared, either by Knoevenagel condensation of substituted cyanoacetylpiperazines with p-aminobenzaldehydes or by carbonyldiimidazole-promoted coupling of phenylpiperazines with p-a
