  In contrast to the facile formation of fac-[Re(CO)3(dpk)Cl] 1 from the reaction between [Re(CO)5Cl] and dpk [(C5H4N)2C(O)], in refluxing toluene, [Re(CO)5Cl] was recovered unchanged when di-2-pyridylamine, dpa [(C5H4N)2NH], was allowed to react with [Re(CO)5Cl] under a variety of conditions. However, a mixture of [Re(CO)5Cl] and PPh3 in refluxing toluene followed by a CH2Cl2 solution of dpa gave cis-[Re(CO)2(PPh3)(dpa)Cl]. The intermediate involved appears to be a general synthon for the binding of the ReI(CO)2(PPh3)Cl chromophore to a variety of bi- and mono-dentate nitrogen-donor ligands and has been utilized to isolate cis-[Re(CO)2(PPh3)(dpk)Cl]. Nucleophilic addition of water at the carbonylic carbon atom of co-ordinated dpk in 1 and cis-[Re(CO)2(PPh3)(dpk)Cl] resulted in the hydration of the keto group and formation of fac-[Re(CO)3(C5H4N)2C(O)(OH)}] and cis-[Re(CO)2(PPh3)(C5H4N)2C(O)(OH)}]. The compounds isolated exhibit rich electrochemical and photochemical properties and the potential application of fac-[Re(CO)3(dpk)Cl] as an electrochemical sensor for electrophiles and Group I and II metal ions is demonstrated.

  与在回流的甲苯中通过反应[Re(CO)5Cl]和dpk [(C5H4N)2C(O)]方便地形成fac-[Re(CO)3(dpk)Cl] 1不同，当二-2-吡啶胺dpa [( )2NH]在各种条件下与[Re(CO)5Cl]反应时，未改变的[Re(CO)5Cl]被回收。然而，将[PPh3]与[Re(CO)5Cl]混合在回流的甲苯中，然后再加入dpa的CH2Cl2溶液，得到了cis-[Re(CO)2(PPh3)(dpa)Cl]。所涉及的中间体似乎是ReI(CO)2(PPh3)Cl色团与各种双齿和单齿氮供体配体结合的一种通用合成单元，并已被用于分离cis-[Re(CO)2(PPh3)(dpk)Cl]。在1和cis-[Re(CO)2(PPh3)(dpk)Cl]中，水对配位dpk的羰基碳原子进行亲核加成，导致酮基的水合以及fac-[Re(CO)3( )2C(O)(OH)}]和cis-[Re(CO)2(PPh3)( )2C(O)(OH)}]的形成。分离的化合物表现出丰富的电化学和光化学性质，并展示了fac-[Re(CO)3(dpk)Cl]作为电化学传感器用于电亲物及I、II族金属离子的潜在应用。
