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.
