Structure and properties of lithium n-butyl amidinates

Popis výsledku v původním jazyce

Lithium n-butyl amidinates (formally lithium salts of N', N-disubstituted amidoimides of pentanoic acid) with various substituents were prepared and characterized in solution by (1)H, (7)Li, (13)C and (15)N NMR spectra parameters in C(6)D(6), THF-d(8) and Et(2)O-d(10). The characteristic spectral parameters were compared with parent carbodiimides and amidines prepared by hydrolysis, where large solvent effects were described. Five of studied compounds were studied by X-ray diffraction techniques in thesolid state. Lithium n-butyl amidinates containing less bulky substituents like isopropyl or cyclohexyl crystallize with Et(2)O or THF as centrosymmetric dimers with mutually parallel amidinate moieties. The lithium N,N'-bis[2,6-di(propan-2-yl) phenyl]n-butylamidinate crystallizes from Et(2)O solution as an asymmetric dimer. The first unit is composed by one ligand coordinated to one of lithium atoms. The lithium atom is also coordinated by one of the nitrogen atoms of the second ligand.
