Abstract A new class of cationic Pd(II) complexes of the type [Pd(Tz)(Cl)(bipy)]+Cl− and [Pd (Tz)(Cl)(phen)]+Cl− (Tz = 1,4-diaryl-3-methyl-1,2,3-triazol-5-ylidene, bipy = 2,2′-bipyridine and phen = 1,10-phenanthroline) with various wing tip groups were synthesized from the corresponding 1,2,3-triazolium… Click to show full abstract
Abstract A new class of cationic Pd(II) complexes of the type [Pd(Tz)(Cl)(bipy)]+Cl− and [Pd (Tz)(Cl)(phen)]+Cl− (Tz = 1,4-diaryl-3-methyl-1,2,3-triazol-5-ylidene, bipy = 2,2′-bipyridine and phen = 1,10-phenanthroline) with various wing tip groups were synthesized from the corresponding 1,2,3-triazolium iodide via the corresponding chloro bridged dinuclear complexes [(Tz)(Cl)Pd(μ-Cl)2Pd(Cl)(Tz)]. The synthesized cationic complexes were screened for their catalytic activity of hydration of alkynes and found to be excellent towards the selective conversion of internal alkynes to the corresponding 1,2-diketones in good yields. A plausible mechanism was proposed for this conversion.
