摘要

In a separate experiment, 0.30 g (0.0015 mol) of the initial distillate, 0.60 g of sodium acetate, 0.40 g (0.0036 mol) of semicarbazide HC1, 4 ml of water, and 7 ml of ethanol were combined. After standing for 7 days, 0.11 g (0.00043 mol, 28%) of 3-methyl-2- phenylcycloheptanone (14) was isolated from the mixture as its semicarbazone: mp 210.5- 213"; nmr (CDC13) T 6.74 (d, benzyl hydrogen). This represents a 20% yield based on 17. ...
