摘要

A series of four, five and six-coordinated magnesium derivatives integrating with substituted pyrrole and ketimine ligands are conveniently synthesized. Reaction of two equiv of 2-dimethylaminomethyl pyrrole with Mg[N(SiMe3)2]2 in THF affords the monomeric magnesium complex Mg[C4H3N(2-CH2NMe 2)]2 (THF)2 (1) in high yield along with elimination of two equiv of HN(SiMe3)2. Similarly, the reaction between two equiv of 2-t-butylaminomethyl pyrrole and Mg[N(SiMe 3)2]2 in THF renders the magnesium derivative, Mg[C4H3N(2-CH2NHtBu)] 2(THF)22(2) in good yield. Interestingly, reaction between two equiv of 2-t-butylaminomethyl pyrrole and Mg[N(SiMe3) 2]2 in toluene, instead of THF, generates Mg[C 4H3N(2-CH2NHtBu)]2 (3), also in high yield. Furthermore, the assembly of two equiv of ketimine ligand, HOCMeCHCMeNAr (Ar = C6H3-2,6-iPr2) and Mg[N(SiMe3)2]2, yields five-coordinated magnesium derivatives, Mg(OCMeCHCMeNAr)2(THF) (4) and Mg(OCMeCHCMeNAr)2(OEt2) (5), using THF and diethyl ether, respectively. All the aforementioned derivatives are characterized by 1H and 13C NMR spectroscopy as well as 1, 3, 4 and 5 are subjected to X-ray diffraction analysis in solid state.
