TMEDA and its ethyl-substituted analogue, TEEDA, show a different behavior toward the deprotonation with lithiumalkyls. While TMEDA mainly undergoes alpha-lithiation of its methyl group, TEEDA shows selective beta-lithiation with following elimination of ethene. The crystal structure of the monomeric intermediate

N,N, N',N'-Tetraethylethylenediamine undergoes simple or double intramolecular dealkylation reactions in the presence of the complexes [RuCl2(diene)]n (diene = cod, nbd) or trans-[RuCl2(diene)(morfoline)2 at 80 degrees C to afford chelating amine ligands which contains one or two N-H functionalities.

The copolymerization of biorenewable succinic anhydride (SA) with propylene oxide (PO) is a promising way to synthesize biodegradable aliphatic polyesters. However, the catalytic systems for this reaction still deserve to be explored because the catalytic activity of the reported catalysts
