To a solution of ketoester 1 (10 mmol) in abs. benzene (30 mL) sodium (0.24 g, 10.5 mmol) was added, and the mixture was stirred for 3–4 h until sodium dissolved. 这句话中abs. benzene是什么意思？ To a suspension of cyclopentenone 4h (0.10 g, 0.30 mmol) in a mixture of 10%-solution of KOH in water (1 mL) and ethanol (1 mL) corresponding aldehyde (0.45 mmol) was added. The reaction mixture was refluxed for 2 h, poured into water (10 mL), the precipitate was filtered off and washed with water (2 × 10 mL) and petrol. ether (2 × 10 mL) and recrystallized from the ethanol-water mixture. In the case of ferrocenaldehyde the reaction mixture was poured into water (10 mL) and extracted with ethyl acetate (2 × 20 mL), the combined extracts were washed with water (2 × 20 mL), dried with magnesium sulfate and evaporated in vacuum, the residue was purified by column chromatography eluting with petrol. ether/ethyl acetate 6:1. 这段话中ferrocenaldehyde 什么意思？ |
