Synthesis, characterization and selective oxidation using a new copper (II) Schiff base complex derived from Alanine and 4-chloro3- formyl coumarin

Autor: Malihe Ebrahimpour, Ghodsieh Bagherzade, Ali Akbar Sajadi, Rouhollah Khani

Publikováno v: Iranian Chemical Communication, Vol 6, Iss Issue 3, pp. 218-324, Pp 228-241 (2018)

A novel Schiff-base ligand (L: 2-[(4-chloro-2-oxo-2H-chromen-3-ylmethylene)-amino] propionic acid) was prepared from the reaction of 4-chloro3-formylcoumarin and alanine amino acid. Copper (II) complex was synthesized from the reaction of the ligand
