Correction: Synthesis, dynamic NMR characterization and XRD studies of novel N,N’-substituted piperazines for bioorthogonal labeling

In the original article an incorrect caption for Figure 1 was given. The assignment of the solvents to the capital letters was not correct. The correct caption of Figure 1 is: ¹H NMR spectra of compound 3a measured in five different solvents: (A) acetonitrile-d₃, (B) methanol-d₄, (C) acetone-d₆, (D) DMSO-d₆ and (E) CDCl₃ (orange: region of interest). Figure 1 with the corrected caption is given below.
