  1 - Synthesis of novel tridentate ligand-based palladium catalyst and investigation of its reactivity towards Suzuki, Sonogashira and Heck coupling reactions
  Rajendran Nagarajan Panneer Selvam Rajeswari Lourdusamy Emmanuvel
  We have demonstrated a simple and efficient route for the synthesis of a novel imine based tridentate ligand and its Pd-complex to investigate the C-C cross-coupling reactions, that involve column chromatography purification in only one step. The catalytic activity of t أکثر

  We have demonstrated a simple and efficient route for the synthesis of a novel imine based tridentate ligand and its Pd-complex to investigate the C-C cross-coupling reactions, that involve column chromatography purification in only one step. The catalytic activity of the newly synthesized catalyst was studied for the Suzuki, Sonogashira and, Heck cross-coupling reactions under mild conditions. All synthesized molecules are thoroughly characterized by IR and NMR techniques. The pro-ligand was characterized by a single Crystal X-ray diffraction study. The catalyst has excellent activity and good yield was obtained with minimum catalyst loading. The obtained yields are good to excellent. تفاصيل المقالة

  2 - Synthesis of functionalized aryl-alkenes catalyzed by CN-ortho-palladated complex of 2,3-dimethoxybenzaldehyde oxime under microwave irradiation
  Fatemeh Rafiee Abdol Reza Hajipour
  A new dimeric orthopalladated complex was synthesized via reaction of 2,3-dimethoxy benzaldehyde oxime with palladium chloride and lithium chloride in methanol as solvent and sodium acetate as base at room temperature. The catalytic activity of this dimeric [Pd{C6H2(-CH أکثر

  A new dimeric orthopalladated complex was synthesized via reaction of 2,3-dimethoxy benzaldehyde oxime with palladium chloride and lithium chloride in methanol as solvent and sodium acetate as base at room temperature. The catalytic activity of this dimeric [Pd{C6H2(-CH=NOH)-(OMe)2-2,3}(µ-Cl)]2 complex as an efficient, air, and moisture tolerant catalyst was investigated in Mizoroki–Heck cross coupling reaction of various aryl halides and also arenesulfonyl chloridesas the electrophilic partners with different coupling partner alkenes such as methylacrylate, methylmetacrylate and styrene . The combination of homogenous metal catalyst, microwave irradiation, and microwave-active polar solvents gave high yields of functionalized aryl-alkene products in short reaction times. تفاصيل المقالة
