previously reported isomer PdLCl2(c) that exhibited a different structural arrangement. The three crystalline structures showed trans/syn, trans/anti and cis/syn relationships in relation to the Cl–Pd–Cl angle and the hydrogen atoms at the HN–Pd–NH moieties, respectively. In addition, DFT computational studies revealed the trans/syn isomer to be the most stable conformation by 5.8 kcal mol−1 and allowed the

catalyst for the copper-, phosphorus-, and solvent-free coupling reaction of terminalalkynes with different acylchlorides in the presence of triethylamine as base, at room temperature and underaerobicconditions. The simple, mild, and green procedure, short reaction times, and moderate to excellent yields make this method well-suited for ynonesynthesis. Graphical Abstract .
