이용 예

CpE Rh Complex catalyzed Oxidative Annulations

To a 13.5-mL screw-cap vial bottle is added AgSbF6 (6.9 mg, 0.020 mmol), Rh complex (0.0050 mmol), Cu(OAc)2・H2O (8.0 mg, 0.040 mmol), acetanilide (1, 0.200 mmol), diphenylacetylene (39.2 mg, 0.220 mmol), and acetone (1.0 mL) under air in this order. The mixture is sealed and stirred at room temperature under air for 16 h. The resulting mixture is diluted with ether, filtered through a silica gel pad, and washed with EtOAc. The solvent is concentrated under reduced pressure and the residue is purified by a preparative TLC to give 2.

CpE Rh Complex catalyzed Oxidative Olefination

To a test tube is added acetanilide (0.800 mmol), AgSbF6 (13.7 mg, 0.0400 mmol), Rh complex 1 (8.5 mg, 0.0100 mmol), Cu(OAc)2•H2O (16.0 mg, 0.0800 mmol), and acetone (2 mL) under air in this order. After stirring 30 min at room temperature, olefin (0.400 mmol) is added to the mixture. The mixture is sealed and stirred at room temperature for 16 hours. The resulting mixture is filtered through a silica gel pad, and washed with EtOAc. The filtrate is concentrated under reduced pressure and the residue is purified by a preparative TLC to give products (up to 82% yield), followed by isomers (<18%).

Derivatization of CpE Rh Complex

To a mixture of [CpERhCl2]2 (21.3 mg, 0.0250 mmol), AgBF4 (19.5 mg, 0.100 mmol), and CsOAc (9.6 mg, 0.050 mmol) in CH2Cl2 (1 mL) is added olefin (1) (0.100 mmol). After the mixture is stirred for 3 h, insoluble precipitates are removed by filtration with a glass filter. To the resulting solution is added brine (3 mL), and this mixture is stirred for 5 min. The aqueous layer is extracted with CH2Cl2, and the combined organic extracts are concentrated under reduced pressure. The resulting residue is dissolved with Et2O and filtered by a glass filter. The solution is concentrated and dried under vacuum to afford a desired complex (2).
