Synthesis of Volatile Copper(II) β-Diketonates, β-Ketiminates, and β-Diiminates. The Problem of Synthesis of Copper(II) Bis(2,2,6,6-tetramethyl-3-methylaminoheptane-5-onate)

The methods of synthesis of the copper(II) beta-diketonates, beta-ketiminates, and beta-diiminates containing in the composition CH3, CF3, C(CH3)(3), and Ph substituents were summarized. At the formation of metallocycles with 2,2,6,6-tetramethyl-3-methylaminoheptane-5-one ligand the intraligand repulsion of tret-butyl group and the methyl group at the nitrogen atom is noted, impeding the complexation.
