Reactions were carried out using standard Schlenk line techniques under nitrogen unless otherwise noted. Column chromatography was performed using 60 Å pore size 230–400 mesh silica gel (Sorbent Technologies) and 58 Å pore size activated neutral alumina (Sigma-Aldrich). All solvents used such as ethylene glycol, dichloromethane and hexane used were reagent grade. Tetrahy-drofuran (THF) was distilled from sodium benzophenone ketyl. Acetone and ethylene glycol were purchased from Fischer Scientific and VWR International, respectively. Ruthenium dodecacarbonyl, triphenylphosphine and dimethylphenylphosphine (Strem Chemicals) 2,2′-bipyridine, 4,4′-dimethyl-2,2′ebipyridine 2-phenylpyridine, 2-(p-tolyl)pyridine (Sigma-Aldrich) were used without further purifications. N,N-Diisopropylethylamine (DIPEA) was purchased from MP Biomedical LLC and Rhodamine-B needed for measurement of quantum yield was purchased from Sigma-Aldrich. The starting complexes K+[Ru(CO)3(TFA)3]− and Ru [(CO)2(TFA)2(PPh3)2] were synthesized according to literature procedures [1 ].

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
