The reaction mixture was heated at 80C for 5h. Then, another portion of H-G catalyst (19mg; 0.03mmol) was added and the reaction mixture was heated at 80C for additional 5h. Then, the solvent was evaporated and crude solid was purified by column chromatography on silica gel (mobile phase – 3% ethyl acetate in cyclohexane, Rf of products 0.18-0.25). In some cases, stated in each experiment, HPLC had to be used due to very close retention time of product and starting material (mobile phase – 0.5% ethyl acetate in cyclohexane).

In a glove box, NHC ligand precursor 23 (63 mg, .13, mmol), ruthenium precursor 11 (78 mg, .13 mmol) and KOMJu(Fe) (29 mg, .13 mmol) were combined in toluene. The flask was sealed, removed from the glove box and stirred at 60 0C for 18 hours. The reaction was concentrated and purified by flash column chromatography (5% –> 20% Et2O/Pent). There were 3 bands that could be isolated from this column, first 2 brown bands and then one green band. The second brown band was the desired product; however, it was not completely pure after one column. Recolumning in 10% Et2O/Pentane gave a brown oil product completely pure by 1H NMR (9 mg, 9%) and another fraction still slightly impure (18 mg, 18%).
