“…[36][37][38] Ruthenium(II) compounds, in conjunction with a variety of oxidants, such as iodosobenzene, methylmorpholine N-oxide, 2,2,6,6-tetramethylpiperidin N-oxyl (TEMPO), bromate, hypochlorite, peroxides, are widely used as the oxidation catalysts. [39][40][41][42][43][44][45][46][47] We have evaluated the catalytic efficacy of compound 2 for alcohol to aldehyde oxidation and aldehyde olefination reactions, and the results are presented in Tables 2 and 3. Treatment of benzylalcohol (1 mmol), TEMPO (2 mmol) and catalyst 2 (0.01 mmol) provided benzaldehyde in 78% yield at 808C after 6 h ( Table 2, entry 1).…”
