Palladium-Promoted Carbon–Nitrogen Bond Cleavage in 1,3,5-Triazinane Derivatives

Abstract

trans-Dichloropalladium(II) complexes with amino acid esters PdCl2L2 have been synthesized via selective hydrolytic cleavage of the nitrogen–carbon bond in 1,3,5-tris(ethoxycarbonylmethyl)- and 1,3,5-tris[(S)-1′(methoxycarbonyl)ethyl]-1,3,5-triazinane under the action of palladium(II) in methanol or in water–acetone mixture. The nucleophilic attack of water or methanol results in selective cleavage of the 1,3,5-triazinane ring in the complexes of palladium(II) with the starting triazinanes, affording the dichloropalladium(II) complexes with amino acids esters.
