MBr(CO)(3){k(2)(N,O)-pyca}] [M = Mn(1a),Re(1b),pyca =吡啶-2-甲醛]和[MoCl(eta(3)-C3 H4 Me-2)(CO)(2){k(2)(N,O)-pyca}](1c)与氨基酸β-丙氨酸反应,得到相应的亚氨基吡啶配合物2a-2c。同样的方法从γ-氨基丁酸(GABA)(3a-3c)和3-氨基苯甲酸(4a-4c)得到亚氨基吡啶衍生物。对配合物2a-2c、3a、3c和4a的固态结构进行了X射线晶体学测定,揭示了它们在固态时氢键模式的有趣差异。(C)2007 Elsevier B. V.保留所有权利。
MBr(CO)(3){k(2) (N, O)-pyca}] [M = Mn(1a), Re(1b), pyca = pyridine-2-carboxaldehyde] and [MoCl(eta(3)-C3H4Me-2)(CO)(2){k(2) (N, O)-pyca}] (1c) react with aminoacid beta-alanine to give the corresponding iminopyridine complexes 2a-2c. The same method affords the iminopyridine derivatives from gamma-aminobutyric acid (GABA) (3a-3c) and 3-aminobenzoic acid (4a-4c). For complexes 2a-2c, 3a, 3c and 4a, the solid state structures have been determined by X-ray crystallography, revealing interesting differences in their hydrogenbonding patterns in solid state.
