“…Among other significant applications, piperidine derivatives are used as analgesics [1] and anti-bactericides [2] or used to treat schizophrenia, Parkinson and Alzheimer diseases [3][4][5]. Metal complexes with ligands containing the six-membered saturated heterocyclic ring were also found to have important catalytic or pharmacological applications [6][7][8] and, therefore, it is not surprising that strong efforts are being devoted to the synthesis of new organometallic compounds containing at least a piperidine ring [9,10].…”
