None:
A series of novel complexes with the general formula [RuNO(NH3)2(L)(NO3)]2+, where L is a bidentate ligand (bpym, bpy, or phen), were synthesized and characterized. trans-(NO, NO3) and cis-(NO, NO3) isomers were identified in the solid state (SCXRD) and in DMSO solution (1H NMR and IR spectroscopy). Their photochemical activity in DMSO was quantified under 450 nm irradiation using a flow-through system, allowing simultaneous IR and UV-Vis spectral monitoring. Quantum yields for photoinduced release of NO were determined to be 4.0 ± 0.8% for [RuNO(NH3)2(bpym)(NO3)](NO3)2 (1), 7.3 ± 0.2% for [RuNO(NH3)2(bpy)(NO3)](NO3)(PF6) (2) and 3.1 ± 0.1% for [RuNO(NH3)2(phen)(NO3)](NO3)2 (3).

Alkynes to Aldehydes and Ketones: Hydroboration-Oxidation
One of the convenient methods for the preparation of aldehydes and ketones is via hydration of alkynes. Hydroboration-oxidation of alkynes is an indirect hydration reaction in which an alkyne is treated with borane followed by oxidation with alkaline peroxide to form an enol that rapidly converts into an aldehyde or a ketone. Terminal alkynes form aldehydes, whereas internal alkynes give ketones as the final product.
Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
