Description
Summary:The synthesis of a six-membered cyclopalladated complex by activation of a Caliphatic-H bond is reported. The synthesis of this organometallic compound is simple and does not require any special equipment, such as gas cylinders, vacuum lines, or solvents distilled over sodium-benzophenone. This experiment shows that certain organometallic complexes are stable enough to be obtained in acetic acid, under reflux, in the absence of an inert gas atmosphere. Most of the signals that appear in the 1H and 13C NMR spectra of the palladium metallacycle can easily be assigned. In addition, the NMR spectroscopy of organometallic and coordination complexes show that the coupling with other nuclei, such as 31P, should be considered.
