Popis: | A series of N-substituted iminopyridine ligands (L1-OH - L3-iPr) based arene-Ru(II) complexes with general formula [(η6-arene)Ru(N,N'-R")Cl]+ was synthesized and characterized by NMR, mass spectrometry, and single crystal X-ray diffraction studies. The synthesized arene-Ru(II) complexes showed high activity for the regioselective Markovnikov hydration of a range of aromatic and aliphatic terminal alkynes and produced moderate to good yields of corresponding methyl ketones. Moreover, the studied Ru(II) catalysts showed good recyclability. Mechanistic studies of the Ru(II) catalyzed hydration reaction was investigated in detail by performing mass experiments and control experiments followed by the identification of crucial Ru(II)-alkyne and Ru(II)-vinyl organometallic species. |
