Abstract
In contrast to the facile formation of fac-[Re(CO)3(dpk)CI] 1from the reaction between [Re(CO)5CI] and dpk [(C5H4N)2C(O)], in refluxing toluene, [Re(CO)5CI] was recovered unchanged when di-2-pyridylamine, dpa [(C5H4N)2NH], was allowed to react with [Re(CO)5CI] under a variety of conditions. However , a mixture of [Re(CO)5CI] and PPh3 in refluxing toluene followed by a CH2CI2 solution of dpa gave cis-[Re(CO)2(PPh3)CI chromophore to a variety of bi- and mono-dentate nitrogen-donor ligands and has been utilized to isolate cis-[Re(CO)2(PPh3)(dpk)(CI]. Nucleophilic and cis-[Re(CO)2(PPh3)(dpk)CI] 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)CI] as an electrochemical sensor for electrophiles and Group I andII metal ions is demonstrated....
