The first structurally characterised sodium primary amide complex; synthesis and crystal structure of 2-PhOC6H4NHNa·NMe[(CH2)2NMe2]2

Abstract

The compound 2-PhOC₆H₄NHNa·NMe[(CH₂)₂NMe₂]₂has been synthesised by a 1 : 1 reaction of sodium hydride with 2-phenoxyaniline in toluene in the presence of N,N,N′,N″,N″-pentamethyldiethylene-triamine (pmdien); X-ray crystallography revealed a solid-state structure comprising a near-symmetrical Na₂N₂ ring dimer with each sodium cation chelated by a tridentate pmdien ligand in an unprecedented near-planar conformation.
