The aqueous one-step reaction of Re(CO)(3)(H(2)O)(3)(+) with pyridine-2-carboxyaldehyde and glycine or alanine produces a new class of cyclic dimeric products. The ligands of the chiral C(2)-symmetric products are bound via the diimine at one rhenium centre and via the pendant carboxylate to a second rhenium center.
Re(CO)(3)(H(2)O)(3)(+)与吡啶-2-甲醛和甘氨酸或丙氨酸的一步水相反应生成了一类新的环状二聚产物。手性 C(2)对称产物的配体通过一个铼中心的二亚胺和通过一个侧挂的羧基与第二个铼中心键合。
