Lithiation of TMEDA and its higher homologous TEEDA: Understanding observed α- and β-deprotonation
TMEDA and its ethyl-substituted analogue, TEEDA, show a different behavior toward the deprotonation with lithiumalkyls. While TMEDA mainly undergoes α-lithiation of its methyl group, TEEDA shows selective β-lithiation with following elimination of ethene. The crystal structure of the monomeric intermediate of this β-lithiation, tBuLi·TEEDA, and theoretical studies indicate kinetic favoritism for the β-lithiation. Copyright

METHOD FOR PRODUCING N-MONOALKYL-SUBSTITUTED ALKYLENE AMINE
PROBLEM TO BE SOLVED: To provide a method for producing an N-monoalkyl-substituted alkylene amine especially useful for uses such as medicine intermediates, agrochemical intermediates, urethane resin-foaming catalysts, surfactants and the like among alkyl-substituted alkylene amine compounds from an alcohol and an alkylene amine as raw materials. SOLUTION: This method for producing the N-monoalkyl-substituted alkylene amine is characterized by reacting the alkylene amine with a ≥2C alkyl alcohol in the presence of a copper-containing oxide catalyst system. The N-monoalkyl-substituted alkylenamine is produced in high conversion and in N-monoalkylation selectivity.

Anodic Oxidation of Amines. VIII. Oxidation of Ethane-1,2-diamines
Anodic oxidation of ethylenediamines (ethane-1,2-diamines) was investigated by cyclic voltammetry and controlled potential electrolysis in aqueous carbonate buffer (pH 10) at a glassy-carbon electrode.The first wave of the diamines is developed at a lower potential than that of the corresponding β-alkanolamines.Among the oxidative bond cleavages, the relative amount of (α)C-(β)C bond fission is larger than that observed for β-alkanolamines and oxidative deamination is only observed after the (α)C-(β)C bond fission.A scheme for the reaction processes is proposed.Keywords: ethane-1,2-diamine; anodic oxidation; (α)C-(β)C bond fission; C-N bond fission; carbonate buffer; glassy-carbon electrode.
