Mono- and bis-ortho-chelated lithium and sodium phenolates. Molecular structures of the first lithium phenolate with a stable, trinuclear structure and of a tetranuclear sodium analog, [MOC6H2(CH2NMe2)2-2,6-Me-4]x (M = Li, x = 3; M = Na, x = 4)

Abstract: The lithium and sodium phenolates of 2-[ (dimethylamino)methyl]phenol, la and 2a, 2-[(dimethylamino)methyl]-4,6-dimethylphenol, l b and 2b, and 2,6-bis[(dimethylamino)methyl]-4-methylphenol, IC and 2c, respectively, have been synthesized. The structures of these complexes in solution were studied by variable-temperature lH and l3C NMR spectroscopy and cryoscopic molecular weight measurements. The solid-state structures of complexes IC and 2c derived from 2,6-bis[ (dimethylamino)methyl]-4-methylphenol, were det… Show more

“…[17] The closest structural analog to 1 is the complex [4-Me-2,6-(Me 2 NCH 2 ) 2 C 6 H 2 ONa] 4 , in which the ''pincer phenolate'' ligands coordinate to three sodium centers of a Na 4 O 4 cubane. [18] However, the phenolate possesses approximate D 2 symmetry, whereas 1 is rendered closer to C 2 symmetry due to the ''secondary'' chelation of the iPrO groups.…”
