Fig. 3: Selective formation of Cr(CO)3-benzophenone complex.
From: Asymmetric hydrogenation of 1,1-diarylethylenes and benzophenones through a relay strategy
Arene exchange reactions between (naphthalene)Cr(CO)3 (2) and an array of benzophenones. Reaction conditions, unless otherwise stated: benzophenones (0.10 mmol), 2 (0.15 mmol), dioxane (1.0 mL), N2, 80 °C, 24 h. a2 (0.11 mmol). Ratios were determined by 1H NMR spectroscopy.
