In air, hydrated ethanolic (95%) solution of 2-(aminomethyl) substituted pyridine and quinoline, on stirring with half equivalent of Cu (OAc) 2· H2O, respectively afforded [Cu (bpca)(OAc)(H2O)]· H2O (1) and [Cu (bqca)(OAc)(H2O)](2){bpca= bis (2-pyridylcarbonyl) diimide ion and bqca= bis (2-quinolylcarbonyl) diimide ion} in good yields. These reactions involve oxidation of the methylene group and formation of the bond between nitrogen and ...
