Figure 13 illustrates two models used to explain the photochemical properties of rhenium carbonyl complexes. The MLCT absorption band often... 

Rhenium carbonyl complexes were used as probes in biological systems. Photoexcitation of [Re(phen)(CO)3(H83)]+AzM2+ and [Re(phen)(CO)3(H107)] + AzM2+ (Az = Pseudomonas aeruginosa azurin M = Cu or Zn) in the presence of the oxidative quencher, Co(NH3)5C1, resulted in the formation... 

I have always regarded the work of my co-worker H. Schulten (66) on the synthesis of rhenium carbonyl complexes as a landmark in our work.

The CO stretching vibrational bands of rhenium carbonyl complexes are useful spectroscopic probes for studying their electronic excited states. As these IR absorption bands reside in the frequency region where few absorption bands exist, their absorption cross section are large and the band frequencies are greatly influenced by the amount of electron density on the central rhe-nium(I). Therefore, transient IR absorption (TR-IR) measurements should be one of the ultimate tools for the study of the photophysics and photochemistry of the rhenium carbonyl complexes.

Wolf and Wrighton have recently reported a rhenium carbonyl complex coordinated to poly[5,5 -(2-thienyl)2,2 -bithioazole] (80) [160]. Electropolymerized films of 5,5 -(2-thienyl)2,2 -bithiazole exhibit an elec-... 

Some iV-alkylation reactions catalyzed by other noble metal catalysts have also been reported. In 2011, Gusev and co-workers reported an Osmium complex-catalyzed N-alkylation of amines at 200 °C with a low catalyst loading (0.1 mol%) [122]. In 2014, Zhu and co-workers disclosed a [ReH7(PCy3)2]-catalyzed amination of alcohols with anilines under CO atmosphere (Eq. 29) [123]. The authors proposed that coordination of CO with Re might lead to decomposition of ReH7(PCy3)2 to a rhenium carbonyl complex, which was believed to be the active...
