Route of Synthesis (ROS)
Conditions | Yield |
Stage #1: 1,2,3,3-tetrachlorocyclopropene; benzene With aluminum (III) chloride In dichloromethane at -78 – 20℃; for 4h; Inert atmosphere; Sealed tube; Stage #2: With water In dichloromethane Inert atmosphere; Sealed tube; | 85% |
Stage #1: 1,2,3,3-tetrachlorocyclopropene; benzene With aluminum (III) chloride In dichloromethane for 0.5h; Stage #2: With water; sodium hydroxide In dichloromethane at 20℃; for 1.5h; Experimental Procedure 4.2. General procedure for the synthesis of cyclopropenones General procedure: The AlCl 3 (0.67 g, 5 mmol) was added by portions to a solu- tion of one of the compounds 2a-d (25 mmol) and tetrachloro- cyclopropene (12.5 mmol) in anhydrous CH 2 Cl 2 (200 mL) un- der continuous stirring for 30 min. The stirring was continued for another 90 min at room temperature, then the mixture was poured in cold water (200 mL). The organic layer was sepa- rated, washed with water (2 ×50 mL) and dried with MgSO 4 . After the solvent was distilled offin vacuo , the residue was chromatographed on Al 2 O 3 using a hexane-CH 2 Cl 2 (3:1) mix- ture as eluent to afford compounds 2,3-diphenylcyclopropenone 3a , yield, 1.64 g, 7.8 mmol (63%), m.p. 120-121 °C (lit.: m.p. 121-121.5 °C [32] ), 2,3- bis (4-methoxyphenyl)cyclopropenone 3b , yield, 2.23 g, 8.4 mmol (67%), m.p. 153-154 °C (lit.: m.p.153-155 °C [33] ), 2,3-diferrocenyl-cyclopropenone 3c , yield, 4.5 g, 10.6 mmol (85.3%), m.p. 182-184 °C (lit.: m.p. 182-183 °C [20] ), 2,3-diruthenocenylcyclopropenone 3d , yield, 3.8 g, 7.5 mmol (60%), m.p. 256-258 °C (lit.: m.p. 256-257 °C | 63% |

Stage #1: 1,2,3,3-tetrachlorocyclopropene; benzene With aluminum (III) chloride In carbon disulfide; dichloromethane at -78 – 20℃; Inert atmosphere; Stage #2: With water In carbon disulfide; dichloromethane Inert atmosphere; Experimental Procedure 2,3-Diphenylcyclopropenone (8b) [1,3]. In a 100 mL one-necked round-bottomed flask fitted with a septum, 1.6 mmol (0.285 g) of tetrachlorocyclopropene and 3.38 mmol (0.45 g) of aluminum chloride (AlCl3) were placed and 25 mL of dichloromethane (freshly dried over NaH) were added. The flask was cooled in an acetone/dry ice bath to 78 °C and stirred with a magnetic stirrer under argon atmosphere. A mixture of 3.2 mmol (0.25 g) of benzene and 2.5 mL of dry CH2Cl2 was added dropwise to the reaction mixture. After the benzene solution was completely dropped in, the mixture was magnetically stirred at 78 °C for 2 h and then allowed to warm to room temperature. The mixture was further stirred for 24 h and after that time, a portion of water was added, and the resulting solution was extracted twice with CH2Cl2. The organic layer was separated and washed with water and brine. The solvent was evaporated and the crude product, after recording the 1H NMR spectrum, was purified on a SiO2 column using a mixture of petroleum ether and ethyl acetate (ratio 4:1) as the eluent. The major fraction containing crude 8b was separated in 74% yield as pale-brown crystals. The product was not purified but used directly as obtained for the synthesis of thioketone 6b; therefore, the calculated yields of both 8b and 6b are unreliable. Pale-brown crystals; m.p. 119-121 °C (after washing with PE) (ref. [1], m.p. 120-121 °C). 1H NMR (600 MHz, CDCl3): d 7.70-7.73 (m, 6CHarom); 7.79-8.05 (m, 4CHarom). | |
